Date: Tuesday, August 20, 1985 Source: By Ann Marie Lipinski. Section: CHICAGOLAND Copyright CHICAGO TRIBUNE TOP DIVER GETS DEATH FOR GANG KILLING Mario Flores was a nationally recognized diver, an athlete who his Whitney Young High School swimming instructor said was one of the best he had ever coached, a young man with ``Olympic potential`` who had a string of scholarship offers from Ivy League colleges. Monday, Flores, 20, was sentenced to death by the same jurors who last week convicted him of the murder of a rival gang member. Flores sat silently as the jury, after three hours of deliberations, returned the verdict to a courtroom filled with his family members and those of Gilbert Perez, 21, the man he is convicted of slaying on New Year`s Day, 1984. According to police and prosecutors, Flores and a friend tricked Perez into entering their car early that morning by claiming that they were members of closely aligned gangs. Perez, who was drunk, had just driven into a car near North and Western Avenues and was attempting to flee. Instead of sheltering Perez, however, Flores drove him several blocks away to an alley behind a factory, where he shot him in the head and chest and ripped the gold chains from his neck.
