A/N: So here's Part 2 of my story and, from here on, things take a turn for the worse… Warning: Please do not read any further if suggestion of sexual assault is distressing to you.

PART 2
Chapter 1

It was Monday morning and JJ was presenting a new case to the team.

"These five women were abducted and found murdered some days later in and around the DC area over the past two years." She pointed a remote control at the large screen on one side of the room and photos of four blonde women appeared, one by one, as JJ said their names. "Emma Carey, 37, was a stay-at-home mom, went missing on September 4th 2007 after dropping her son off at Clifton Elementary School in Clifton, Virginia. She was found on September 7th, having been tortured, beaten and then strangled." Susan Maycroft, 39, worked at a bank, she disappeared September 9th from the parking lot at Northgate Plaza Mall in Silver Spring and was found September 12th. Abigail Stone, 38, was a high school teacher, abducted September 4th 2008, found September 8th; and Corinne Baker, 39, was a lawyer and she went missing on September 9th and was found on the 13th. They had all been beaten, tortured and then strangled." She pressed the remote again and, this time, the photos showed the corpses of these women, bruises covering their faces and bodies.

"Wait, so there was no evidence of sexual assault?" asked Reid.

"The first two didn't exhibit any signs but Abigail Stone and Corinne Baker were raped post-mortem," replied JJ. The team all paused to take this in.

After a few moments, JJ continued. "They were all taken from parking garages and dumped in the Potomac River." Pressing the remote again, the photos disappeared, to be replaced by that of a pretty brunette. "Three days ago, on September 4th, Tania Greyton, 30, was taken. She was found this morning by two fishermen in Piscataway Creek," a picture of Tania appeared on the screen, her body caught in reeds on a river bank, bruised and strangled "with the same injuries as the other women."

"He's changed his victimology," said Emily, looking slightly bemused. "The latest victim's a brunette and at least seven years younger than the first four. Are they sure it's the same unsub?"

"Although it's rare for an unsub to change his preference, it's not completely unheard of," Reid informed the room. "Kenneth Bianchi murdered women of all different races, ages and appearance."

"Yes but it's strange that he should kill four blondes in two years and then switch to a brunette this year."

"Well, given where they were taken from and where they were found; the type of injuries; the post-mortem violation; and the date pattern, the Arlington PD, who are heading up the investigation, are pretty sure this latest murder is connected to the previous four," JJ replied to Emily's query. "They'll know more when the coroner has had a look at Tanya."

"Were the bruises inflicted over the whole four days?" asked Morgan.

"Yes, the coroner's reports say that the women were beaten repeatedly over a period of time."

"There doesn't seem to be any obvious connection between the women's lives: a stay-at-home mom, a bank employee, a teacher and a lawyer," said Hotch. "JJ, what did the latest victim do for a living?"

"She was a barmaid."

"Okay, so they all appear to be from different socio-economic backgrounds. Reid, I want you and Garcia to look deeper, see if you can find some sort of a connection between them."

Reid nodded and said, "I'd also like to map out a geographical profile of where the women lived and worked and where they were abducted from – there may be a pattern in that."

"Fine," said Hotch. "Rossi, you and Morgan go to Piscataway Creek and see what you can get from the body – I know it may not be much; Prentiss, I want you to talk to the victims' families – Reid you go with her; JJ and I'll go straight to the precinct to meet with the lead detective. I think it may be useful for us to stay on-scene so bring your go-bags with you; we leave in thirty minutes."

It was less than an hour's drive to Arlington and the team made their way to their various assignments. Hotch and JJ arrived at the Arlington police station and were met by the chief officer on the case. He was a blond man of average height and stocky build with an open face which was smiling as the two agents approached him.

"Captain John Kleinman?" asked JJ, holding out her hand. "SSA Jennifer Jareau, we spoke on the phone. This is SSA Aaron Hotchner."

The Captain shook Hotch's hand after relinquishing JJ's and led them into the station. "I'm glad you agreed to come," he said. "Although I'd hoped there'd be more of you."

"Our colleagues are out in the field already – we don't want to lose any time as he's going to be taking another victim in a couple of days," replied Hotch.

Kleinman showed them into a small room with three desks and a board which was covered with photos and documents pertaining to the case. "You can use this room as your base of operations," he said, and the two agents began to set up their gear.

Morgan and Rossi pulled up outside the Ranger's office at Piscataway Park to find the Ranger waiting for them. He greeted them as they stepped out of the SUV.

"You the gentlemen from the FBI?" he asked.

"Yes I'm Agent Rossi, this is Agent Morgan," the older man replied, shaking the Ranger's hand.

"John Tucker; Park Ranger. Well, shall I take you straight to the body?"

"Yes please," said Rossi.

The Ranger led them into the park, through some woods for about half a mile until they heard the sound of running water. The path then began to slope downwards, gently at first but getting steeper the nearer to the river they got. Finally they reached the bank which was cordoned off with a long line of yellow crime scene tape and ducked under it.

They immediately spotted the body which was floating in the shallows of a small inlet where the water's flow was interrupted and an accumulation of twigs, leaves and some litter swirled around it. A man had just finished examining the body and Tucker introduced them:

"Gentlemen, this is Doctor David Ambrose, the coroner. David, these are the agents from the BAU: Agents Rossi and Morgan." They shook hands with the coroner and began their questions.

"Can you determine the time of death?" Rossi asked.

"Well, I can say she's been in the water for approximately five hours but, given all the variables that water presents, I'd be reluctant to give you a ToD with any more accuracy than eight to fifteen hours ago."

"Does she exhibit the same type of injuries as the other victims?"

"Yes, the bruising on the face and body shows a timeline of a few days, plus the marks on the neck appear to be consistent with the previous victims but I'll have to measure the hand span when I get her back to the morgue."

"Of course," replied Morgan. "And she was found just like this – there's no evidence of her being weighted down and no attempt to hide her identity or keep her from being found?"

"None that I can determine at this stage. Of course, I'll let you know if I find anything to the contrary later."

The two agents thanked the coroner and conferred between themselves.

"So, he makes no attempt to hide what he's done or to whom," began Rossi. "He obviously doesn't care what happens to them after he's finished with them. They're disposable once he's had his fun."

"Yes, which means he probably has no personal connection to them," Morgan replied.

"And that's going to make our job that much harder."

It was getting late by the time the team reconvened back at the precinct to collate their findings. Reid and Prentiss had talked to the families of all the victims but had not found any connection between them, other than the first four all being similar in age and appearance.

"Are we absolutely sure that Tania Greyton was killed by the same unsub?" asked Prentiss, desperate for something – anything – to make sense in this case.

"Yes," replied Rossi. "The coroner has confirmed that the hand marks around each victim's neck was identical, including Tania's."

There was a pause while everyone took this information in and integrated it with what they already knew.

"Okay," began Hotch, taking the lead. "So we know that he targeted blonde women in their late thirties and then he switched to a brunette who was a number of years younger. There has to have been a trigger to have caused him to change his victimology like that: I don't think that's random."

"Well," said Rossi, his thoughts obviously forming just a little ahead of his mouth speaking them. "He's throwing them away when he's done with them; they're effectively garbage once they're of no use to him anymore so why be so picky in the first place?"

"The blondes definitely represented something or someone to him," added Reid. "It may be that he's devolving if that physical similarity doesn't hold any sway for him anymore."

"You know, he probably targeted those women specifically to begin with which would have meant a lot of time watching them," Morgan put in.

"Yes but none of the families or co-workers were able to remember anyone hanging around or any suspicious vehicles," was Reid's reply.

"And what about Tania Greyton?" asked Emily. "Did he watch her and target her specifically? Or was she taken on the spur of the moment?"

"Well, if he is devolving, he could take just about anyone next time."

"And he'll also begin to lose sense of his timetable and may continue to abduct more women even after his customary two this time around," Emily finished, her eyes wide in shock.

"Yes," agreed Hotch. "And we don't have much time before he'll be onto his next victim."

A/N: Okay, I'm not massively happy with that last scene but I felt something was needed there and couldn't hold this chapter up any longer so decided to go ahead and post it so we could all move forward – sorry everyone!

A/N 2: I have tried to be as accurate as I can with regards to the methods used by the BAU and the psychology of the killer but I only have an amateur's knowledge of these things so please forgive me any mistakes! I'm sure John Douglas would pick this apart in no time, LOL!
