Chapter 10

16:00pm

The young detective leaned forward and grabbed the edges of the sink as he emptied his stomach's contents into it. His shoulders was shaking and his face was paler than the white tiles of the bathroom floor. One of his buddies was next to him, patting him on the back and comforting him.

Iruka gave him a sympathetic glance as the guy passed him, his hand still over his mouth and his cheeks slightly tinted green. His friend lead him out and away from the horrifying crime scene of the Sandman's thirteenth victim.

Everywhere was blood. Blood on the walls, blood on the carpets, blood on the furniture, even blood on the ceiling. Iruka didn't blame the fresh first year as he himself felt sick too. He could hardly bare to look at the disfigured and mutilated body of the young man on the floor. His eyes were open and dull. Lifeless green orbs stared at Iruka and he was sure that if the guy was still alive, he would have been able to see a great amount of fear and terror in them.

''Dang, I'm guessing this guy was afraid of a knife or something.'' Naruto said from where he was crouching next to the victim and examining the handle of a butchers knife.

''It's not guaranteed that this is one of the Sandman's vics.'' Sakura said thoughtfully as she took another picture before she went over to Kiba in the kitchen.

''Mn, still. It's in Bos-sing-say so there's a pretty good chance. Hey, Shikamaru! What did the landlord say?'' He called over his shoulder to the lazy detective talking on the phone. Shikamaru Nara was a tall, lanky young man with spiky black hair and studs in both ears. He wore a tight fishnet shirt and an open grey shirt over it along with blue jeans and sandals.

Shikamaru sighed and hung up before he went to Naruto. He pointed his notebook in the direction of the body and said:

''Shun Fabré. Age 24. Works at the Sugarshack across the street as a part time waiter. No family in this area but has a cousin somewhere in Moscow.'' The spiky haired investigator said as he poked at something on the wall, most likely a bug.

Iruka, who was standing at the doorway to avoid the rusty smell of the blood, stared intently at the knife in Shun's chest. The victims face was completely distorted and he couldn't even make out if the body still had a nose or not. All that was visible was his frozen eyes.

Shikamaru went over to Iruka and cocked his head.

''Hey… Are you feeling alright? '' He asked and leaned against the wall, pulling a face when some of the blood came onto his shirt but since he was already full of it, he didn't really care. ''You look a little green.''

Iruka smiled a faint smile at him.

''Nah, I'm fine. Its just kind of…''

''Disgusting?'' Shikamaru offered.

''Yeah.'' He said and looked away.

''S'okay, kid. You'll get used to it.'' Shikamaru said reassuringly. ''It's too bad this guy was afraid of knives. It would have been a whole lot less easier if he was afraid of rubber duckies or something. But knives? How troublesome.'' He muttered and Iruka frowned.

''I don't think he was afraid of knives.'' Iruka said and this caught the attention of Naruto, Sakura and Kiba.

''What do you mean?'' Asked Naruto. ''Of course it's knives. Why else would the Sandman have stabbed him so many times?''

''Well, Shun Fabré worked as a waiter.'' Iruka started. ''Why would he be afraid of knives if he works with them every day?''

Shikamaru looked surprised as did Naruto and Sakura. Kiba looked back to the body and scowled, thinking carefully. He then turned back to the other with a smile.

''Oh, I get what your getting at.'' He said at Iruka who nodded. ''Shun wasn't afraid of knives, he was afraid of blood.'' Kiba said excited and then went back to the body, checking him over to see if this new found information could lead to new evidence.

''Exactly. It's known as Hematophobia. It's quite common actually but this must have been an extreme case.'' Iruka stated and went over to the body as well, studying the knife.

He then went to the kitchen and started searching through the cabinets. Moments later he returned with a block set of knives of which the biggest one was missing.

''Looks like Sandman used one of Shun's own knives to kill him. He most likely kept him alive for a while, just to get him to see the blood. Since there's no sign of forced entrance, there's a good chance that the Sandman is someone that wouldn't be of much suspect. An everyday person. it could be a neighbour, a security guard, even the mailman.'' Iruka said and ran his fingers through his hair, forcing himself to keep his composure as Naruto pulled on the knife, creating a sickening sound. Shikamaru grinned and clapped his hands together.

''Hey, not bad for a second year. Stick with me kid, I'll make you famous. Come on, lets go to Tsunade.'' He said and hooked his arm around Iruka's neck, leading him outside.

''Hey Cap! Dolphin boy found something.'' He said as he pushed Iruka towards her before he ran around the back of the house, minutes later appearing with a massive dog in his arms.

''Looks like Shun had a puppy.'' He said and Tsunade rolled her eyes. The dog looked closer to a small bear than a big dog and was busy chewing on Shikamaru's sleeve.

''Shikamaru, that's not a puppy, that's a mutt. Now get it away from me! I'm allergic to dogs.'' She said and waved him away before she went to Iruka.

The front yard of Shun Fabre's house was a neat, well-kept, average lawn. It had a sturdy fence and the gate was locked when they got here. The dog was also in the front, barking at the door. Two of the cops had to lock him in the back after he tried to attack, or rather, eat them. The front door was locked as well and they had to kick it open. Everything was normal and the security was good, meaning this wasn't a high risk victim at all.

''Shoot.'' Tsunade said to Iruka as they walked around the house to check all the windows.

''Okay. COD is excessive blood loss. He basically died because of his injuries, which is a blow to the head and multiple stab wounds. Murder weapon, a Butcher's knife. His own. If this was the Sandman, he used his fear against him, the same MO. We suspect his fear was blood. As in, Hematophobia. But it wasn't his fear that killed him, like with the other cases. It was the knife. Not like the girl that was drowned or the man that was burned. With them it was their actual fears that caused their death. Since blood can't kill you, the Sandman probably used a knife to finish the job.''

''Ah but see, the blood did kill him. The lack of it, anyway.'' A voice said from somewhere behind them, startling both.

Iruka and Tsunade spun around, searching for the source of the voice. They found nothing and gave each other a puzzling look.

''Up here.'' They heard again and the two of them looked up into the huge oak tree, meeting the pale, amused eyes of Neji Hyuga. Tsunade growled.

''Neji! You almost gave me a bloody heart attack! What are you doing up there?'' She snapped at the Hyuga, who just gave her a smirk.

While Tsunade was yelling at Neji, Iruka was pondering over how on earth Neji got into the tree. Eventually he accepted that trying to figure it out would be a lost cause and focussed his attention back to Tsunade.

Tsunade shook her head.

''Why do I always get the crazy ones? Neji's in the tree, Naruto is raving the vic's fridge, Gai didn't show, Kiba's bothering the cat and Shikamaru is playing with the vic's disgusting mongrel.'' Tsunade's tone was both joking and frustrated. ''Alright Neji, care to explain what you're doing in the tree?''

''Looking for a better view.''

Tsunade rolled her eyes.

''No, I'm serious.'' Neji said and stood up. ''I can see the backyard. There's a shed, a birdbath, an empty aviary, a lawnmower-''

''Neji, skip to the point!'' Tsunade snapped impatiently and Iruka too wondered what Neji was getting at. The Hyuga continued with his list, undisturbed by Tsunade's exasperated tone.

''There's two dog houses.'' He finally said and leaned forward, grabbing on one of the branches for support.

This newly found material swirled around in Iruka's mind. Two dog houses but only one dog. Unless this dog is one of those highly adored, pampered pooches, he can't imagine why the dog needs two houses.

If there was a another dog, he didn't make an effort to show himself.

''Uhh, Tsunade?'' Shikamaru called as he came up to them, the massive mutt still in his arms.

Tsunade turned around and gave the lazy man a disapproving look.

''Didn't I tell you to get rid of it?'' She snapped and took a step back after shooting the poor dog a very dirty look, giving Iruka the impression that she was afraid of the dog, rather than allergic to it.

''You might wanna look at this.'' Shikamaru said and picked up the dog's left front paw, holding it up so that she could see.

The dog's tips of his toes were covered in a red liquid. Blood. But there was no evidence of an injury, meaning that the blood did not belong to the dog. Said dog seemed happy to get some attention and wagged his tail, sending flying drops of blood in all directions. Shikamaru placed him on the ground and pointed at the tip of the canine's waving tail. There was also blood.

''He got into the house?'' Tsunade asked confused as she examined the dog's paws and tail from a distance.

''Not exactly… Um, this may be a little upsetting to some of you but they found another body… In the shed. There was two dogs and the Sandman killed one and hid it in the shed. He was stabbed.'' The tone of Shikamaru stated that he though that killing the dog was unnecessary, cruel and cold-blooded. Iruka agreed.

If there was one thing he hated, it was animal abusers. The dog didn't mean any harm. He was just protecting his owner but the Sandman had to go and stab him. Why did he leave the other dog? Was this one not a threat? Or does this killer feel the need to show that he can kill the tougher one of the two?

None of this made sense.

The Sandman was starting to show heavy signs of someone who doesn't know what he wants. That could indicate that he's new. If the body of the dog had multiple stab wounds, it could have been an overkill, meaning that he was inexperienced.

Iruka made a few mental notes, reminding himself to discuss it with Hatake.

Hatake.

This person had been on his mind ever since they met. The next appointment wasn't going to be any time soon so he still had a lot of time to figure out Hatake's so-called puzzle. He decide that it would be easier to find Reason first, then Cause. Right now, Solution doesn't seem like it would ever be found. But he couldn't give up. Its already obvious that the police won't find the Sandman by tracking a pattern, as Kakashi had said. No, this person handles his kills like he would a hobby. The general idea stays the same but the method differs.

Iruka was snapped from his thought when Kiba waved a hand in front of his eyes.

''Dude, hey dude, snap out of it.'' He said and gave Iruka a concerned look.

Iruka blinked and shook his head. He gave an apologetic smile at the dog boy.

''Sorry Kiba, I got lost in thought. Were you saying something?''

''Nah, it fine. Tsunade say we can go home. The forensics didn't find much but that's no big surprise. They're doing autopsy's at the lab and we can start working on this tomorrow.'' Kiba said and sighed.

''Are you okay?'' Iruka asked worried.

Kiba gave him a faint smile.

''I'm fine. I just don't get why that bastard would kill a dog. And then his owner.'' He said sadly and absentmindedly stroke the remaining dog's head, who was sitting next to him.'' But I guess that's why we lock these guys up. Bunch of freaks.'' He muttered and then lit up again. ''Well at least now I have a new buddy.'' He said happily and picked up the enormous mutt with much ease.

Iruka smiled. Kiba must care a lot for dogs. He mentioned he had nine. This one was going to be number ten.

''I'm sure you'll take great care of him.'' Iruka said as he cautiously reached out to touch the dog's head, avoiding to look at the long fangs.

Kiba gleamed as if Iruka had just told him that he won a million dollars.

''Really? Thanks pal, that means a lot! Oh I cant wait to show him to Akamaru and Maximum and Chicago and Hamachi and Lollop and Pace and…''

Iruka listened gleefully at Kiba's cheerful rant as he told him about all his dogs. By the time they said goodbye, it was already dark. The crime scene was horrible, Shikamaru even mentioned that it was one of the worst he saw in years. The case rest heavily in the mind of the two detectives as they individually parted. Neither one of them saw the two eyes watching their every move…
