The rest of Thursday Morgan and Rossi try to get as much information out of their prisoner as they can but he reveals very little. Garcia has been able to pull death records in Alaska for over 200 women who fit the victimology. Reid, Hotch, JJ and Emily spend the day doing background checks and calling family members of the women trying to track 'the Master' that way. Around 4 p.m. Cheryl Runningwater comes into the conference room.

"We finally got Gabriel's prints. My guys are running them now."

"Good. If nothing pans out get a copy to Garcia. We have access to a few more databases than you and may be able to find something."

"Sounds good."

"Chief Runningwater," Reid says standing up. "The areas that you helped us discount as kick off points, do you think a path could have been concealed in both of them?"

"Yeah, no problem. If they do it far enough off the road. I mean, none of us are going to traipse into thick brush on the off chance a psycho has decided to cut a trail to the river."

"So we need to check out those places." In addition to the first two places Cheryl had discounted, several more possibles had come out of a second search and some had also been eliminated by the chief.

"So we have 7 places in addition to the first to check." Hotch glances at his watch. "Obviously not tonight. But we need to check them tomorrow or Marielle dies on Saturday."

"Morgan and I can take the east side of the river," Emily offers.

"Good. Reid and I will take the west side," Hotch looks Cheryl. "If we can narrow down possible drop sites, would it be possible to get a helicopter scrambled on Saturday, just in case someone ends up in the river?"

"Yeah, no problem. The big bosses want this taken care of. We can also have boats on stand by at various points on the river just in case," she adds.

"Perfect. Let's get Rossi and Morgan and call it a night. We have a lot of hiking to do tomorrow."
