'Mama, I killed Dean,' confesses Elmer Wayne Henley Jr. 'Dean' refers to serial killer Dean Corll, who murdered at least 28 teenage boys and young men in Houston between 1970 and 1973. As Corll's accomplice, Henley lured victims to Corll's home and participated in several murders. Henley fatally shot Corll on August 8, 1973. He then called 911 to confess.

This television news coverage for Houston’s KPRC-TV chronicles the immediate aftermath. Reporter Jack Cato first follows Henley and police to the storage shed where Corll buried several victims. At the scene, Henley uses the radio telephone in Cato's car to call his mother. Henley and David Owen Brooks, another Corll accomplice, then lead investigators to burial sites near Lake Sam Rayburn and on High Island Beach. Between August 8 and 13, the buried remains of 27 victims were found across the three locations. The grave of another known victim, Mark Scott, remains undiscovered. Back in Houston, the family of 15-year-old William Ray Lawrence, one of the four victims found at Lake Sam Rayburn, holds a funeral.

Henley was convicted of six murders and sentenced to six consecutive life terms. Brooks was convicted of one murder and sentenced to life imprisonment. The series of crimes became known as the Houston Mass Murders.
