Beyond forensic evidence, the case was solidified by the harrowing testimony of Jennifer Asbenson, a woman who managed to escape after being kidnapped and tortured by the killer.

The sources conclude by noting that the decades-long pursuit of justice ended in 2018 when Urdiales committed suicide while on death row in San Quentin.
