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.
