of the rented boat shed. In each of these abductions, Brooks is known to have been a participant. One of these three victims, 15-year-old Randell Harvey, was last seen by his family on the afternoon of March 9 cycling towards Oak Forest, where he worked part-time as a gas station attendant. Harvey was driven to Corll's Mangum Road apartment, where he was subsequently killed by a single gunshot to the head. The other two victims, 13-year-old David Hilligiest, and 16-year-old Gregory Malley Winkle were abducted and killed together on the afternoon of May 29, 1971. As had been the case with parents of other victims of Corll, both sets of parents launched a frantic search for their sons. One of the youths who voluntarily offered to distribute posters the parents had printed offering a monetary reward for information leading to the boys' whereabouts was 15-year-old Elmer Wayne Henley—a lifelong friend of Hilligiest. The youth pinned the reward posters around the Heights and attempted to reassure Hilligiest's parents that there might be an innocent explanation for the boys' absence. On August 17, 1971, Corll and Brooks encountered a 17-year-old acquaintance of Brooks named Ruben Watson Haney walking home from a movie theater in Houston. Brooks persuaded Haney to attend a party at an address Corll had moved to on San Felipe Street the previous month. Haney agreed and was taken to Corll's home where he was subsequently strangled and buried in the boat shed. In September 1971, Corll moved to another apartment in the Heights: 915 Columbia Street. Brooks later stated he had assisted Corll in the abduction and murder of two youths during the time Corll resided at this address, including one youth who was killed "just before Wayne Henley came into the picture." In his confession, Brooks stated the youth killed immediately prior to Henley's involvement in the murders was abducted from the Heights and kept alive for approximately four days before his murder. The identities of both of these victims remain unknown. Participation of Elmer Wayne Henley In the winter of 1971, Brooks introduced Henley to Corll. Henley likely was lured to Corll's address as an intended victim. However, Corll evidently decided the youth would make a good accomplice and offered him the same fee of $200 for any boy he could lure to his apartment, informing Henley that he was involved in a "white slavery ring" operating
