Defense expert: Iowa murder suspects confession unreliable
At the end of the interrogation, Rivera told police he followed Tibbetts while she was running. Prosecutor Scott Brown blasted Leslie, the defense expert, for failing to consider evidence that corroborated Riveras confession. Brown noted that Rivera was able to lead officers after the interrogation several miles to the cornfield where her body was found. Police questioned Rivera after tying him to a car that was seen on surveillance video circling Tibbetts while she ran. Two of Riveras relatives testified Thursday that they were denied access to him when he was being questioned.
