Criminology students at the University of Texas at Arlington have aided Arlington Police in a breakthrough for a 1991 cold case. The students' review of evidence led to the arrest of Janie Perkins, charged with capital murder in the death of Cynthia Gonzalez, who disappeared in September 1991 and was found with gunshot wounds. The students identified Perkins due to failed polygraph tests and a lack of alibi, prompting renewed police investigation.
