The Harris County medical examiner believes she has found another victim of 1970s-era serial killer Dean Corll, who murdered 27 boys in Houston and was killed himself by one of his teenage accomplices.

Forensic anthropologist Sharon Derrick said the victim was identified through DNA analysis as Joseph Allen Lyles, who was 17 when he disappeared in February 1973. Lyles' body was found 16 years ago on a beach in nearby Jefferson County, and buried in a manner similar to Corll's other victims.

In the early 1970s, Corll and his two accomplices, Elmer Wayne Henley and David Brooks, tortured and killed their victims, then buried then in makeshift graves in a Houston storage unit and on beaches in nearby counties. Lyles would be the 28th victim found, if the investigation shows he was killed by Corll.
