A Markham man was charged Saturday after he allegedly shot a man at a 7-Eleven in Tinley Park.
Christopher Dyson, 18, was charged with first-degree murder and armed robbery after he allegedly shot and killed Thomas Mastro, 24, during an argument at the 7-Eleven around 3 p.m. Thursday, officials said.
The two men reportedly met up to exchange an iPhone for a PlayStation in a deal made on Craigslist, according to police.
Mastro, of the 6900 block of Coachwood Trail in the south suburb, suffered a gunshot wound to the chest in the shooting at 167th Street and Oak Park Avenue, the medical examiner’s office said. His death was ruled a homicide.
Dyson was reportedly arrested after a 45-minute manhunt that involved Tinley Park, Oak Forest, Orland Park and Cook County Sheriff’s police.
Dozens of squad cars, plus at least two ambulances, responded, ending up in the vicinity of 147th Street and Oak Park Avenue near Oak Forest.
