first, the defense brought up the original suspect, abbass esfehani. recall he was the victim's former boyfriend, described as hot-tempered, who made a hasty return to iran in the days after the murder. esfehani's fingerprints were found on the banister leading up to the murder scene. >> i'm telling you straight out, the guy was cold about it. >> and the exchange student's former roommate remembered a strange reaction when esfehani discussed cheryl miller's death. >> i remember saying to him, you're acting as if nothing even happened. >> okay. >> it was really -- it was shocking to me that he could care less. >> what do you think really happened to cheryl miller? >> well, i think the most plausible theory, in my opinion, is that abbass esfehani was the one that committed the crime. they were lovers. they had just broken up a week before. she had called her parents -- this is in police records -- a very bad blowout. >> what do you think happened? >> well, miss miller was not only beautiful, but she was very bold. and mr. esfehani was from a country cult
