te shep? >> shepard: trace, kutcher was testimony was key to the time line. >> yes. he spoke that he spoke to ashley on the night of the murder telling her he would be late. he said it wasn't a problem. she just got out of the shower and had to dry her hair. her roommate found her in the next day outside the bathroom and the hair dryer was still plugged in on the toilet. kutcher got to the house, saw the blood that he thought was wine. so the killer had a very small window of opportunity to commit the crime and hi just happened to live in the neighborhood. the suspect is on trial for attempted murder in 2008 and also believed to have killed a 18-year-old female in 1993 in his hometown of chicago.
