13 and 20 were found buried at the three locations Henley (and later, Brooks) had stated they and Corll had buried the victims, with an additional victim being discovered in 1983. Seventeen of the victims were found buried in the boat shed, a further four victims were found at Lake Sam Rayburn, six bodies were found buried at High Island Beach (although the body of a seventh victim buried at High Island, Mark Scott, still lies undiscovered at this location) and the body of a 28th victim was found buried at Jefferson County Beach in August 1983. All the victims found were young males and many had been sexually tortured in addition to being sexually assaulted. Autopsies revealed each victim had been killed by either strangulation, shooting or a combination of both. At Henley's trial in 1974, one of the six bodies found buried at High Island, that of 17-year-old John Manning Sellars, was disputed as being a victim of Corll by a forensic pathologist who examined his remains. The youth, who vanished on July 12, 1973, had died of four gunshot wounds fired from a rifle, whereas each other victim of the Houston Mass Murders had either been strangled or killed with the .22 caliber pistol Henley had used to kill Dean Corll. However, Henley and Brooks had led police to Sellars' body on August 13, 1973, and the youth's body was found bound hand and foot and buried in a manner similar to Corll's other known victims. Indictment On August 13, 1973, a grand jury convened in Harris County to hear evidence against Henley and Brooks. The jury heard evidence from both Rhonda Williams and Tim Kerley, who each testified to the events of August 7 and 8 leading to the shooting of Dean Corll, plus the testimony from various police officers who recited and discussed the written statements each youth had made and described how both Brooks and Henley had led them to each of the burial sites. The assembled jury also heard the testimony of a youth named Billy Ridinger, who had been abducted by Corll, Henley and Brooks in 1972 and who testified as to his torture and abuse at the hands of the trio. After listening to the evidence presented, the jury initially indicted Henley on three counts of murder and Brooks on one count. Bail was set at $100,000. Henley was not charged
