Dyson tried to rob Thomas Mastro, 24, outside the convenience store before pulling a gun, shooting Mastro in the chest and then fleeing the scene north on Oak Park Avenue, police said. He was captured around 147th and Oak Park Avenue in Oak Forest after a 45-minute manhunt by Tinley Park and Oak Forest police, joined by other area law enforcement agencies.

Mastro, of Tinley Park, was shot in the chest. He was taken to Palos Community Hospital in Palos Heights, where he died of the gunshot wounds, the release stated.

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.

We're not legally allowed to protect ourselves in Illinois in any form or fashion. We can't even carry a baton or a stun gun. That is ridiculous. Criminals have it made when they know us normal folk aren't armed with any form of protection.

Remember, every other state has concealed carry laws. Indiana, Wisconsin, Michigan etc... Every state that borders illinois. And yet no one fears traveling to those states regularly. And NONE of those states have any problems with concealed carry. Even if the second amendment was abolished tomorrow, crime would continue and most likely increase because only law abiding citizens would be affected.

The courts have ruled in favor of concealed carry because the argument against it was too weak. Read the ruling yourself its right in there.

Mike F., if law abiding citizens were legally allowed to carry weapons to protect themselves from criminals, it might actually make some of those criminals think twice before it ever came to the situation you described. I'd rather have a chance to protect myself than just stand there and let myself get shot by some thug with a third grade I.Q.
