that rigor mortis set in. i looked at those pictures and can't believe we send an undetermined cause of death and a natural death. >> detective gibson agreed. they had a problem. >> very thin, notes from a medical examiner from eight years before and a few photos, very few in. >> and only two slides were taken by the pathologist and passed on in evidence. so, yeah, very thin time. >> so police went back to the doctor that did that autopsy and asked her to review the case. she did, but she would not alter her original findings. the next step might have been to order a new alms. but that wasn't possible since corey's family had her remains cremated. the only option was to work with what they had. detective gibson had a suggestion. >> he wanted to have the autopsy reviewed by someone else , have it -- basically, a review of the original autopsy done. couldn't do a new autopsy because the body had been cremated.
