Charges in Tinley Park Shooting

A Markham man has been charged in connection with the Thursday shooting of a Tinley Park man during a supposed electronics exchange at a Tinley Park convenience store, prosecutors said Saturday.

Christopher Dyson, 18, of the 16600 block of Winchester Avenue in south suburban Markham, was charged with first degree murder and armed robbery.

Cook County Circuit Judge Laura Marie Sullivan ordered Dyson held without bail Saturday.

Thomas Mastro, 24, of the 6900 block of Coachwood Trail in Tinley Park, had agreed to trade a gaming system for Dyson’s iPhone after Dyson had responded to Mastro’s Craigslist ad, Assistant State’s Attorney¬† Dan Calandriello said in court today.

The two met at a 7-Eleven store in Tinley Park around 3 p.m. Thursday to make the exchange, said Calandriello. Court records show the store is  at 16658 S. Oak Park Ave.

The defendant arrived in a Mercedes, according to Calandriello, and afterwards, video shows Dyson placing a box in the Mercedes. Mastro retrieved the box and the two began to struggle over it, at which time Dyson shot Mastro in the chest, Calandriello alleged.

According to court records, the gaming systems involved were a PlayStation 3 and a PlayStation Vita.

Dyson put the box in his car and sped out of the parking lot and headed north on Oak Park Avenue, Calandriello said.

An eyewitness informed an nearby off-duty police officer who started chasing after Dyson, according to Calandriello. At times, the officer was driving at 90 miles per hour, with Dyson travelling ahead at a faster rate, Calandriello said.

Dyson later lost control of the Mercedes and fled into a forest preserve on foot, Calendriello said.

More than 50 officers from a dozen surrounding communities searched the woods, including six search dog teams and the Cook County/Chicago Police helicopter, police said. The search went on for nearly an hour before two officers stationed at the perimeter of the woods near 143rd Street saw the suspect attempting to leave the woods. The officers, from Orland Park and Oak Forest, chased the suspect into the woods and apprehended him, police said.

Police located a weapon near 159th Street and Oak Park Avenue, police said.

The Cook County Medical Examiner’s office said an autopsy showed that Mastro died of a gunshot wound to the chest.0 markham

      He was such a good boy. He was about to get his GED. He was also a great daddy to his 5 kids with all different mamas. He was set up by that white boy.

    He drives a Mercedes and he steals a used play Station and shot and killed a guy over it. You can't reason over stupidity.

      @ Tired Of The Morons: First of all, my reply was intended for "Fed Up" because for once he was right on target with his responce and he displayed resrtaint with his wording.
      Secondly, Mr. Moron, if you're going to use it, don't be a Coward-ass, Bitch about it and use abbreviations (or much less "the N word), MAN-UP and say it…NIGGER!
      WOW, hiding behind a computer the way your kind hid behind white sheets, and still have no balls.

        The abbreviation is because you can never tell what algorithm they will use to blank words. Hiding behind sheets has nothing to do with these idiots and their complete disregard for common sense and acting like human beings. But hell just to please you and make your evening here it is for you. He's just another dumb nigger acting like an animal in the jungle maiing teh rest of his race suffer for it. Happier now?

PEOPLE ARE ANIMALS NO MATTER WHAT COLOR, and we DO NOT want NO thoughtless animal like him or your kind who ALWAYS are known for massacres NO where in our midst either. HELLO!!!! WHY can't WE ALL just stick together for what's right and putting a STOP to anyone or anything that is wrong and harmful. MY God, look around you people…life is too short.

    Not all situations are equal, this one gets no pity, he acted like a barbaric animal and deserves what's coming to him if not more. I feel sorry for the family of the victim. I hate the insensitive violence from thug mentalities who take away from our humanity as a culture of people by cowardly disregarding honor and trust, humanity for other human beings. I rest with knowing justice comes after death as well! He's history!

    I am an African American man and just like he killed that man he would have done the same to me. I'll be willing to bet a dime to a dollar this is not his first major felony that he has committed. He thought he could get away with by trying a new area. Thank Quinn for abolishing the death penalty, He will get out in 30 years at the 48 and next time he will try a different area and the same results will repeat. No he was not about to get his GED nor was he trying to turn his life around so he is a prime candidate for the death penalty but Quinn knows what is best for everyone!

    As always the lie still lives on " INNOCENT UNTIL PROVEN GUILTY" when it's always been just the other way around ''GUILTY UNTIL PROVEN INNOCENT''. When the real truth is that nobody knows what or why this happened, we just know it happened. Does this give us the right to judge? NO… I believe not the only ones who really know are the defendant, the deceased, and GOD… I'm not saying he is just, I'm not saying he's unjust, I'm simply saying "ONLY GOD CAN JUDGE" so don't crucify the defendant just because it's just not right………. To the family of the deceased my condolences…. To the family of the defendant the same…… But to the f***er dropping the N-bomb yo daughter,wife, or girlfriend probably had some N-bomb in them if you know what i mean. In other words choose your words very carefully partner cause they might turn around on you Mr. KKK on the CPU. you dig it. For those who don't know this is CHI-TOWN !!!

    This is one savage beast who I hope drops the soap in the prison shower repeatedly and gets what's coming to him.
