Chapter Four

The CSIs knocked on the patched-up door to Yami's house and it was answered by a young man with a strange over-to-the-side styling to his blonde hair. He asked them who they were.
"We're Crime Scene Investigators," the woman with short brown hair said in a patient voice. "We're here to look around your friend's room. Where it happened."
"Oh, right," the young man said, frowning. "How's Yami? We haven't heard from 'im since it happened. Is he awright?"
"He went to the hospital for a little, and now he's with his friend, Marik I think he was called."
The young man relaxed and smiled tightly. "He's well looked after, then. I'm Joey, by the way. We haven't been in his room. Come in."
"Thanks," the woman said, and she and her afroed counterpart walked inside, lugging their heavy silver briefcases after them. They found three other young people huddled in the living room watching them with heavy eyes. It looked like they hadn't slept since the night before, since the murder. A young woman in a dressing gown, a young man with a spike of brown hair and a tall young man staring at the floor. They introduced themselves as Tea, Tristan and Seto. They opened their mouths to start asking questions but Joey raised his hands and forestalled their comments.
"He's with Marik, he's okay."
They all seemed to relax slightly and Tea yawned.
"You'll all have to come to the station to give us your statements later," the afroed man said. "The officers who arrived at the scene should have done it, but I think they messed up."
"We weren't here when it happened," Seto said in a low voice. "We were all out for the night and came back afterwards. We left Yami on his own." He clenched his jaw and looked away.
The CSIs looked at each other and just walked into Yami's room on the ground floor by the door, stepping under the police tape. The afroed man closed the also-patched-up door behind them.
"Signs of forced entry," he said wryly, looking at the splintering around the lock and the obvious shoulder and foot marks on the outside.
"Signs of a struggle," the woman sighed, looking at the chaos in the room. It looked as if Yami had tried to hide behind his possessions and had them flung across the room. The bedsheets were rumpled and blood-stained. There was a puddle of blood staining the carpet by the window, and high velocity spatter on the walls. They started processing the room, working from the door to thw window, marking and photographing anything of interest. Eventually there was only the bed left. The woman grimaced and they started straightening out the sheets, after photographing their original state. They took samples of the blood and stripped it down to the base sheet. Turning off the lights, the man scanned over the sheet with his UV torch.
"Three separate semen samples," he said in surprise.
The woman also scanned. "What on earth was going on here?"
"I dunno," the man said grimly. "But someone's not telling the truth."

Meanwhile, the blonde female CSI and the boss had found Bakura Schhadenfroid's house and were opening the door.
"He said the victim dragged him here at knifepoint and raped him, just over a year before now," the woman said, shaking her head. "I don't want to believe it, but my gut says he was telling the truth."
"Mine too," the boss said grimly, leading the way inside. "We see so much of the worst of humanity, it sometimes makes you wonder…"
"Wonder what, Griss?" the woman asked, peering through the first door, into the study.
The boss didn't reply as they stared inside.
The room was covered in blown-up photographs of about five young men around Yami's age, captured in moments of pain and humiliation, all from directly above. They were all bleeding and crying.
"Oh my God," The woman breathed, looking at the pain on their faces. She suddenly pointed to the photographs on the desk and spread most around the room. "That's Yami Motou."
They sorted through the photos. They seemed to be still images from video footage, from the occasional blurring. Yami was tied to the bedpost, wrists raw from pulling at the bonds. His face was streaked with tears and blood running from the cuts on his face. He looked absolutely terrified and in agony. The photos followed the abuse being dealt to him, laid out chronologically. How the knife opened his flesh, how Bakura Shhadenfroid smeared his hands in Yami's blood and struck him. The fresh carving of a letter B onto Yami's hip and then a shot of his face, screwed up and screaming. Soon after he looked like he'd been punched in his mouth to shut him up. There were shots of Bakura's trousers coming off and hitching Yami's legs up, and Yami's petrified face. Then a confused picture with much blurring of Bakura penetrating Yami, and the blood that flowed as a consequence. The shots got even blurrier then, supposedly as Bakura thrust into him.
The very last picture was a skewed angle of a large tanned hand swinging into the field of the camera's view, just at the side. Presumably that was Marik's entrance, and the Victim hadn't wanted to be reminded of the loss of his prey so hadn't put up further pictures.
The woman breathed hard, eyes like stone. "Yami was telling the truth about that first time, it seems." She said grimly, looking at the timestamp on the pictures; a year and a week ago. They looked at the pictures of the other young men, and they all followed the same pattern. The same type of man, youngish and skinny, not too tall, who had taken obvious pride in their appearance. The same pattern of cutting. All with a B carved in their left hip. Only Yami seemed to have been saved, the others had been left tied to the bed for hours afterward, apparently too terrified to sleep. It seemed that Bakura had filmed them and tortured them until he grew bored and let them free.
"Look in here," the boss said, rootling through the drawers of the desk. He had found five large folders, each neatly labelled with a name and a picture of each of the young men plastered to the walls. They found the one for Yami and falteringly looked inside, reminding themselves to be scientists and investigate the scene unemotionally.
Bakura had been stalking Yami for half a year before the rape. Inside were… many more photos, apparently taken from the same phone. Yami and Marik around Domino, Yami on his own, a few Peeping-Tom type pictures. The folder was full of them, and mapped out Yami's routine movements; where he went, what he did, who he met up with. On the back of each picture were notes like, '10.02 met with Spiky Hair outside house. Left for a movie – Superbad. Ate a share box of sweet popcorn and a large Coke. 11.45 left cinema, back to tat. place for sex. Looked hot. Filed under 205.' And there were more pictures, and more and more, on and on in a hideous exercise in obsession.
The woman and the boss exchanged a grim look and went through the other folders.
Bakura had stalked the others too, and it seemed that his obsession hadn't ended when he had raped them. His surveillance continued, with his victims looking a lot less sure of themselves, out in public less often. When they were they were often accompanied by other people, their friends, and seemed ill at ease. All of them had been raped again, from the looks of things, just when they had regained their confidence. The first young man to have received Bakura's attention had more surveillance on him, dated to just a day or so ago.
"I need to step outside," the woman said firmly, feeling sick at heart. The boss waved his permission and she stood in the gritty, fuggy, foul air trying the clear her head. No matter how hard she tried to shut off her emotions, and think of her job to investigate what was, after all, a homicide… she was revolted by what their 'victim' had done. But if she showed it she could compromise the evidence and the case. She had to get her emotions under control and look at things with just her brain. Her boss seemed able to do it, but then he had years of experience on her.
When she had regained her composure she joined her boss inside again, and they moved on through the house. The other rooms were normal and obsessively tidy, except for one room equipped only with a hard bed. The walls were splattered in arterial spray, directed from the bed. This was where he had raped them.

Back at the lab, the CSIs held a meeting that used to be called a Brainstorming Session but, because of Political Correctness, was now called a Case Meeting, where they would try and hammer out the details of the case to find possible answers.
"Let's start with the gun," the boss said, clasping his hands on the table.
The afroed man held up a photo of the bloody-handled gun. "9 millimetre, standard issue. He could have got it anywhere, Trace and Ballistics are still trying to get a serial number off the butt. No fingerprints because of all the blood on the handle, which tested positive as Yami Motou's. Five shots fired, all found in the vic."
"With Yami's blood on the handle, isn't it obvious who fired it? Yami." The brunette woman said.
"Not necessarily," the boss said. "Both their hands were covered with blood, nullifying the test for GSR, and the cops at the scene said Marik was holding Yami when they arrived, trying to stop the bleeding. Either of them could have picked up the gun. Let's move on to other evidence until Trace and Ballistics get back to us on the serial number."
"We found three semen samples on Yami's bed," the brunette woman said, pointing at the relevant photos and DNA reports. "From Yami, Marik and Bakura. The samples from Yami and Marik were slightly degraded, suggesting they happened earlier. DNA said they were probably a week or so old, whereas Bakura's sample was mixed with Yami's blood and most likely made less than an hour prior to his death."
"We found two mobile phones in Yami's room," the brunette woman continued. "One belonging to Yami, the other to the vic. Yami made a call to Marik's phone a few minutes before Bakura's estimated death; Archie's trying to get the sound file. Bakura was filming," she said grimly, not needing to go into more detail. "Archie's trying to find that footage as well, but blood got into the circuits so it might take a while."
"Tox screens from the blood samples?" the boss asked, nodding his thanks to the brunette woman.
"Yami's blood, collected from the bed and the dressings from the hospital, tested negative for all known substances. He doesn't even smoke. Bakura's blood, collected from the floor and body, was positive for cocaine, high grade. We couldn't get a sample off Marik."
The boss frowned. "When you bring them in again, get a sample."
"When?" the afroed man asked, speaking for the rest of the group.
"Soon. What were those other semen samples doing there, and why did neither of them mention it? And interview their friends too, Yami Motou's roommates and Marik Ishtar's roommate Otogi. See if all their stories add up. If we can find out why it appears Yami and Marik were having sex earlier in the week from Bakura Shhadenfroid's death, it could put a whole new angle on things."
"What are you thinking, boss?" the blonde woman asked, hands on hips. "Some sort of jealous love triangle?"
"Exactly," the boss said, waving them out of the door. "Go on, get to work."

Marik frowned at the knocking on the door, blinking awake from his doze. He and Yami had been trying to sleep, wrapped up in each other's arms and tangled in Marik's duvet. Yami's eyes went wide at the knocking, the sound bringing back a few shaky memories of the night before, not quite remembered fully but enough to scare him. Marik gently disentangled himself and went to answer the door; if it were Otogi he would have just come in, so he knew it had to be the police. None of Yami's friends had ever been to the tattoo parlour.
Sure enough, it was them.
"We need to ask you a few more questions," the blonde woman who had originally interviewed them said gently, looking about for Yami. Marik held the door firmly so they couldn't see inside.
"Can't you let him rest? He'd only just gotten to sleep when you all arrived," he said sourly, looking at the team of CSIs and a few policemen.
"Well I'm sorry that's the case," the woman said neutrally, "But we need to ask you both some more questions. If you'd like to fetch him? There's no need to get uncivilised about this. Half an hour or so down at the station and you can come back to rest."
"Fine," Marik sighed, going to try and pry Yami out of his bed. Yami didn't want to get up and needed another dose of painkillers to unwind himself; his limbs had stiffened slightly too, and he broke a few scabs accidentally by moving. Marik had to help him walk to the door and glared at the CSIs as if to say, see the pain he's in? This is your fault.
They took it calmly, however, and escorted them back to the police station.

Yami's roommates were being interviewed.
"What did he tell you about what happened just over a year ago?" The afroed man asked delicately.
The four exchanged looks and shrugged. "Nothin'," Joey said. "He just seemed to change overnight. At first we thought Marik had done sommat to 'im—" he broke off as Tea kicked him reprovingly. "Okay, okay, I thought Marik had done sommat to 'im. He was all quiet and withdrawn and the only person 'oo could bring him outta it was Marik."
"There's no easy way to tell you this," the afroed man said, pushing a photo if the vic towards them. "Just over a year ago, this man kidnapped and – abused – Yami. I understand Marik rescued him."
Tea's hand flew to her mouth and tears filled her eyes. "Poor Yami! He never said a word to us!"
"He probably felt ashamed," Seto said grimly, bitterly. "Just think if you got raped, would you want to tell all your friends?"
"Tell me about the relationship Yami and Marik had after that incident."
"It was peaceful," Tristan said softly, looking at the floor. "I mean, we were used to Yami's usual … type… and sure it was like that before, but after then… it was like Yami needed Marik just to get up and go."
Tea put her hand on Tristan's knee comfortingly. "Yami always needed to be touched, he was a very physical person especially with his boyfriends. But I guess after that night… he kept pulling Marik's arms around him, like he felt safe there."
"So there was no abuse that you saw?" The afroed man asked just to clarify. They all looked horrified.
"No," Seto said firmly. "Marik wouldn't dream of hurting Yami. He was completely committed to him."
"What about their sex life, as lovers?" The afroed man asked a little uncomfortably. He could never get used to asking that.
"I don't think there was any, not for a long time," Tea said quietly, looking at the others for support. "They were certainly very close. Yami was always holding Marik's hand or sitting in his lap or being hugged, but I think the most – sexual – it got for a long, long while was a kiss on the cheek."
"Well," Seto said, an eyebrow quirking up. "Until about a week ago."

The blonde woman pushed a series of photos towards Yami again, the photos she and her boss had found in the folders of Bakura's desk. He glanced down at them and his whole face flamed up from his neck to his ears; he slammed them face-down on the table.
She raised her eyebrows. "It's just you and Marik in there."
"Where – how – did you get those?" Yami asked intently, unable to quite meet her eyes and holding the pictures down as if they fought to show off their contents.
The woman softened slightly. "We found them in the victim's desk. As you know, they predate the first time he raped you."
Yami struggled with words. "He – he was stalking me?" he whispered, the blush fading slightly.
She nodded and gently turned one over, showing a rather intimate picture of Yami with his pants down and Marik's head between his legs, hands on Yami's hips as Yami arched, mouth open in a wide grin, eyes closed. Yami flamed up again and tried to slam the picture over but she whisked it out of the way, looking at it dispassionately.
"Why so embarrassed? It looks like you were having fun."
"How would you feel," Yami said tightly, "If strangers had evidence of you at your most reserved, most vulnerable? At those moments so intensely private you'd never speak of them?" He grabbed for the picture determinedly. "You think because I'm gay I'd feel any different than you, if our positions were reversed?"
The woman relented thoughtfully and let him take the picture and hold it face down with the others. "This was one of the first pictures the victim had of you. It seems to have been the first day he was stalking you, certainly. He must have gotten into the apartment across and had a peek through the windows; you should really close the curtains if you don't want to get spied on, you know."
Yami looked away, shaking slightly in mortification. "What do you want?"
"Tell me about what made that particular day special," she said softly. "Tell me what caused his obsession with you."
Yami licked his lips and stared at the floor as he told her.

It was a few months into their relationship, and the height of summer. They were going strong, having a lot of fun and enjoying being with each other. It was the day of his third-year results, and Yami leaned against the wall by Marik's tattoo parlour, munching on a toffee apple in the warm sunshine. He had looked in and seen Marik was busy with a customer and waited for him to finish.
Soon Marik came out, wiping freshly-washed hands on his work apron. He grinned to see Yami, looking him up and down lasciviously with that sexy look that was never hidden whenever he looked at Yami and made him feel so hot. He stepped up close and bent to lick at the toffee apple, meeting Yami's eyes over the top.
"Enough apple for me?"
Yami grinned slowly, licking at the apple too. "How you can make that sound like an innuendo I have no idea."
"It's a skill," Marik said, one hand trailing down Yami's arm to his hip. Yami stepped closer so their legs were pressed together, only the apple keeping them apart. "Mm," Marik said, eyebrows raised suggestively as Yami pressed up close.
"I got my results," Yami said quietly, biting the apple but looking at Marik the whole time.
"How'd you do?"
"I got all Firsts," Yami smiled, going to take a bite. Instead he found Marik's mouth, sweet like the toffee syrup, and his arms holding him tight, spinning him around until he felt dizzy. Yami pulled away and laughed in pure joy as Marik beamed at him, refusing to let him go and holding him effortlessly, spinning high.
"Gods, well done Yami!" Marik grinned, letting his feet touch the ground again but holding him close, apple forgotten in one hand as he nuzzled Yami's neck. Yami sighed and melted happily, a smug expression on his face.
Next thing he knew, Marik had pulled him up the stairs and locked the door behind them, pushing Yami into his bedroom.
"Wh-what about your shift?" Yami gasped as Marik's hands plunged down his trousers.
"I've got time," he said throatily into Yami's neck, pushing him down to sit on the edge of the bed. Yami complied in a near-daze, surprised by Marik's actions but unable to deny him. "I've always got time for you…"
So saying, he knelt before Yami, between his legs, and attacked his belt with his teeth. Yami groaned as Marik's teeth grazed across his abdomen. Marik pulled the zip down with a startling degree of expertise, hands sliding up Yami's thighs to hold his hips.
"Have you ever had one of these before?" Marik said in a low voice, looking up from Yami's crotch at his flushed face. Yami shook his head, lips parting as blood rushed through his body in an intoxicating rush to pool in his groin. Marik gave a dark chuckle and pulled Yami's pants down. "Then let me give you your first. As a well-done present."
His head dipped lower and his lips parted too, sheathing Yami in his mouth. Yami gave a startled cry at the incredible moist heat of Marik's mouth, giddy and breathless. At that moment Yami's phone rang.
"Don't answer it," Marik mumbled, the vibration of his voice making Yami give that gasping groan Marik so adored to have in his ear. Yami obeyed and the phone soon stopped ringing, only to start again a moment later.
With a frustrated sigh, Yami awkwardly lent down to pick it up and answer. "What is it, Joey?" he asked breathlessly as Marik kept on.
"Hey, how'd ya do?" Joey asked cheerfully.
"All Firsts," Yami gasped. "You?"
"Naw, not quite so good. You okay, Yami?"
"Y-You've got me at an awkward moment, Joey," Yami said, biting his lip to stop the moan that threatened. "Could you ring back a bit later?"
"Whah?"
"I'm with Marik," Yami said tightly, closing his eyes and shaking slightly at the intensity of Marik's mouth and tongue lapping and sucking against his length.
Joey, on the other end, gave a huge "Oh!" of realisation and started laughing. "I'll call ya back then!"
Marik suddenly deep-throated Yami and the phone slipped out of his nerveless fingers to bounce on the floor. Yami cried out, arching his back. With one hand Marik ended the call and sucked hard until Yami released. Yami gasped for breath, chest heaving as Marik chuckled and swallowed the fluid that coursed down his throat in a hot rush.
"G-Gods," he whispered, eyes still closed. He swayed slightly. Marik gently licked up Yami's length then pulled back, sitting next to a rather drowsy Yami and holding him.
"Well done, my sweet," he purred proudly. "You worked hard for those Firsts."
Yami started to laugh.

Yami hadn't told her all the details, of course, but enough. She nodded thoughtfully. "The joy," he murmured to herself. "Yes, that seems consistent."
Yami said nothing, mortified.

Later, the CSIs met again. The blonde woman opened with, "It seems his obsession started when he saw them at their best, and tried to bring them down to rock bottom. Then, with the first young man, right when he was better again the Vic dragged him back."
"That's a bit of a strong conclusion to make," the boss said neutrally. "Let's keep all options open for now."
"What now?" The brunette asked. "It seems we have a Vic we should be glad isn't causing more harm and two potential suspects who can't remember a thing. Allegedly."
"We follow the evidence."

Lame ending is lame, I know. Sorry.
Next chapter will be the last~ Stay tuned folks~ XD
