During Bahena Rivera's trial, the jury heard two wildly contrasting theories of what happened to Tibbetts.

Iowa police investigators testified that they questioned Bahena Rivera after his car, a black Chevrolet Malibu, was captured on surveillance video circling the neighborhood in Brooklyn at the time Tibbetts was last seen alive jogging in the area.

During a lengthy interview, investigators testified that Bahena Rivera allegedly told them he saw Tibbetts jogging and thought she was \"hot.\" They said he claimed to have followed Tibbetts, gotten out of his car and jogged alongside her, but she rejected his advance and threatened to call the police.

Investigators said Tibbetts was stabbed repeatedly but that Bahena Rivera told them he blacked out and did not recall attacking her. He said he later remembered putting Tibbetts' body in the trunk of his car when he noticed her earbuds in his lap while he was driving. He claimed, according to investigators, that he drove to the cornfield and buried Tibbetts body under leaves.

In a stunning twist, Bahena Rivera, who speaks little English, testified in his own defense at his trial, claiming he was kidnapped by two masked and armed men, who forced him to drive to where Tibbetts was jogging and one of them killed her and put her body in his car's trunk.

He claimed he put Tibbetts' body in the cornfield, but did not go to the police because the kidnappers threatened to harm his ex-girlfriend, the mother of his young daughter, if he spoke to authorities.
