So give me your deductions, Pat Brown. Who do you think is responsible? Use all that gray matter you`ve got up there and tell me what you think.
PAT BROWN, CRIMINAL PROFILER, AUTHOR OF "KILLING FOR SPORT": Well, I do agree with the police that it is a local person.
GRACE: Why?
BROWN: Somebody right around.
GRACE: Wait. Wait there, why?
BROWN: Absolutely. Because, first of all, for somebody had a window of opportunity to grab her. I don`t believe he had a vehicle, he`s coming through town where he could have taken her and then zipped right out of town 10, 20, 30 miles and thrown her body in a ditch some place. This guy had to throw her in a dumpster right there. That means he had -- really no way to move it some place else.
GRACE: Why? Why? Why are you saying it was too far away from an interstate? Why?
BROWN: He may not have had a vehicle, that`s one possibility. Or he may have -- just not had time to leave. He had -- maybe he`s doing this on his -- he had to go home perhaps. Somebody expected him. He had to go to work.
GRACE: You know your theory is corroborated by the fact that her body was likely disposed of right there in the area.
BROWN: Exactly.
GRACE: Because that trash was from the neighborhood trash. Yes, it traveled 55 miles to the north, but it came from that neighborhood.
