"Let's go over this one more time. We only know little about the unsub's latest victim. Other than that, we have nothing on his previous ones. Jamie doesn't seem to be a threat – student, a scholar, no bad record," Hotch began the next briefing on the plane.

"That may mean the unsub is acting on a frustration. Maybe he's not good with the ladies, or he sees in them something he has wanted all his life," Rossi continued.

"There's no apparent physical pattern on his victims – there's a brunette, three blondes, a red-head – he's all over the place," JJ said helpfully, again passing around photos of the victims.

"His inferiority to a woman might have stemmed from abuse when he was a child, too. His mother might have made him feel stupid, worthless," Prentiss added.

"Children who grew up in abusive households do tend to act out their frustrations on the people who most reflect their desired life. Take for example Ryan Ambers, the case we worked on a few months back. All the men he killed resembled his favorite actor, because as a kid his parents made fun of him when he said he wanted to be an actor," Reid chimed in.

"How long before Jamie's body was recovered?" Hotch asked JJ.

"Two days. The lockers are outdoors – by the football field – and are off limits to students on weekends, which explains why no one discovered her until after Monday's first gym class," JJ said.

"Reid, tell Garcia to look up names of janitors, electricians, plumbers or any sort of maintenance the school had within the week of her murder. I also need you to work out where he might strike again. Prentiss and Morgan, go over the crime scene. If they struggled, there must be hair or skin still on the crime scene that may belong to the unsub. Rossi, we'll go with JJ and talk to previous detectives who worked the other cases," Hotch looked at the team.

"We need to work fast. The sooner we get the profile out, the better. He might strike again."

The agents filed out of their SUVs, with Hotch taking the lead. A man in his mid-forties was waiting for them outside.

"Detective Michaels? I'm Jennifer Jareau, we spoke on the phone," JJ said.

Michaels offered a handshake. "Adrian Michaels. Nice to meet you Ms. Jareau."

"Please, call me JJ. This is agent Hotchner… and these are agents Rossi, Prentiss, Morgan and Dr. Reid," JJ introduced the team.

"Are Jamie's parents already here?" JJ asked.

"Yeah, they're in my office. Pretty shaken up, but the mother's a tough one," Michaels said.

"Right. JJ, go to them first. Rossi and I can handle the other detectives," Hotch said. "Reid, follow up on Garcia and see if she's come up with names already."
