His parents live in Oak Lawn. Mastro would've turned 25 on March 26, according to public records.
A man who identified himself as Mastro's brother didn't want to talk about the incident when a Patch reporter spoke to him Friday.
Dyson and Mastro met at the 7-Eleven to trade electronics after Dyson responded to Mastro's ad on Craigslist, according to a report of Dyson's bond hearing in the Chicago Tribune. Dyson was to trade his iPhone for a Playstation 3 and Playstation Vita from Mastro, the report continued.
A video of the parking lot shows Dyson putting a box in his Mercedes, the report stated. Mastro then tries to take it back, and the two fight over it, the report added. That's when Mastro was shot, the report stated.
