Section: NEWS Copyright Chicago Tribune ALL APPEALS FAIL; GACY IS EXECUTED SERIAL KILLER DIES OF LETHAL INJECTION John Wayne Gacy, who killed 33 young men and boys in the 1970s, was executed early Tuesday, despite a problem with the lethal injection used to kill him. Hours after exhausting the legal appeals that had filled and perpetuated his life, Gacy, 52, died strapped to a gurney in the execution room at 12:58 a.m. at Stateville Correctional Center near Joliet. Howard A. Peters III, head of the Department of Corrections, said the second of three chemicals that were to flow into Gacy's arm apparently "gelled" or was blocked by a clot of Gacy's blood. Officials attached a new tube to the needle and resumed the execution. The state's $25,000 lethal injection machine releases three chemicals: the first causes sleep, the second stops breathing and the third stops the heart. Executioners had started the chemicals flowing at about 12:40 p.m., and the execution had been expected to take about 10 minutes, not 18. ................................ ------------------------ COPYRIGHT - CHICAGO TRIBUNE This excerpt was obtained from the Chicago Tribune's archives in the Newstand section of AMERICA ONLINE (aol.com).
