Christopher J. Dyson, 18, also faces an armed robbery charge connected to Thursday's shooting that left a Tinley Park man dead. He is being held without bail.

Christopher J. Dyson, 18, of Markham, was charged Saturday with murder and armed robbery in connection with Thursday's fatal shooting in a Tinley Park 7-Eleven parking lot, according to a Village of Tinley Park press release.

He is being held without bail, and his next court date will be Tuesday, March 26, at the Bridgeview courthouse, a village spokesman said Saturday. The case is still under investigation, according to the press release.

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.

Everyone should carry a gun I would rather be judged by 12 then carried by 6 !

Criminals don't abid by the law. We are still the victims. Sitting targets. At least give us a chance to fight b k and save our own life
Watchful Eye March 23, 2013 at 05:40 PM
He is to blame- no one else- he is 18 and is an adult. He made the decision to do what he did, knowing what the consequences are. Now he should pay the price. Save the pity for the family of the poor guy that was killed- he didn't deserve it and was singles out by this Piece of ****!

I think some of us knew the after the fact details of this sad story of a young man from Tinley Park just buying gas at a local business who came across a thug from the outside.RIP Mr. Mastro !

As parents, we try to teach our kids right from wrong their whole lives. There comes a time when they have to make their own choices, though, and this KID made a horrifically wrong one. Now there are 2 lives lost. My prayers go out to BOTH families....and to the precious little boy who was left without a father because of this kid's reasoning that he was OWED what Thomas Mastro rightfully EARNED and found the only answer was to shoot him. The Lord said "a little child shall lead them.." I don't think He meant straight to Hell.

I wonder if Mr. Obama's gun regulations would have had any effect on this boy's life. I think not. Let's disarm criminals, not law abiding citizens.
Tori March 23, 2013 at 05:53 PM
And from the outside, really? Would it have been better if the thug were a resident? The issue is violence and that a man lost his life! Focus on that! Mastro's family has had a tragedy. A human life was taken over possibly a few dollars and you are all talking about the biased media and making racist comments. That dies not honor Mr. Mastro and it won't bring him back. Shame on you. Why not do something useful, like raise money for the unexpected funeral costs his family will face? Because you don't care about him, you just wait for opportunities to wax racist!

I'm with ya there brother! Join the NRA. I did to help ccw in Illinois
Hopeful March 23, 2013 at 06:11 PM
CZK, I agree. My comment about Mr. Obama's plan to disarm the law abiding citizens for some reason was censored. I guess that's nonconducive to someone's thinking. Disarm the criminals, not people who have a right to bear arms.

I wouldn't be surprised if there was more to this story. Our world, however, has taken a terrible turn. We hear on a daily basis the lack of respect for life. It's beyond my comprehension how one human being can walk up to another and just take their life - regardless of the reason. Another example was the little toddler shot yesterday in his stroller with his mom next to him - why? There can be no logical reason.

If you see a young person going down the wrong road, please, please, please get out of their way or you could end up just as dead as Thomas Mastro if the young person is anything like Christopher Dyson.

What are you talking about? Patch has been constantly updating this story.

Tinley park, Markham, and Robbins the only difference is the property tax. People in Tinley are stupid to pay so much for nothing.
Alex garcia March 23, 2013 at 07:01 PM
What an idiot he threw his life away and ended another
Laura March 23, 2013 at 07:09 PM
I am not sticking up for this 18 year old, but you really don't know if he was failed by anyone! I have been failed by many and made wrong choices, but because people who had open hearts and minds we the ones help me over come these failings and bad choices. You are fortunate if your life has not had struggles and challenges and not made some bad choices that resulted in extreme consequences.
JJR March 23, 2013 at 07:10 PM
The vile hatred and ignorance being spewed on this page is sickening. The man is a criminal and it is scary. But god help us all when people with so much hate in their hearts start packin' heat.
Tony b March 23, 2013 at 07:18 PM
Keep it simple. Crime is random as well as a way of life on a daily basis for many. Try him. Lock him up and throw a way the key. Thanks tinley park police for a job well done. To the murderer. Off you go to the criminals convention center Enjoy. To the family. My deepest sympathy and may god rest his soul in peace. I m sure he is in a good place. Love your friends and family as though its your last chance on a regular basis and don't take a minute for granted.

As of 2:00 pm sat. 3-23-13 I have not seen any posting on the internet from our major local news agency"s web page reporting the identity and motive of the suspect for the shooting and killing of the young man from Tinley Park at the 7-11 on 167th & oak park,Wow ! and WHY??
Ellie March 23, 2013 at 07:51 PM
Wouldn't reducing the number of guns on the streets make a bit more sense? How does the logic of "more guns will prevent gun violence" work, exactly? When you're sick with a virus, like the flu maybe, do you figure you'll get better if you give yourself more viruses, like HIV?
Mike Fangman March 23, 2013 at 07:51 PM
Let's say I pull a gun on you. You reach for your gun. Do you think I'm going to wait for you to draw your weapon like in the movies? No! Bang! I shot you, plus I just got your gun.
Mike Fangman March 23, 2013 at 07:52 PM
Please keep your racist comments to yourself.
Ellie March 23, 2013 at 07:52 PM
You'd rather be judged by 12 before you're carried by 6? Good for you, I guess.
Joe Tinley March 23, 2013 at 08:01 PM
Sorry bleeding heart! that's the problem nobody takes responsibility for they're actions, nobody forced him to carry a gun, nobody told him to attempt an armed robbery, nobody told him to shoot and kill an unarmed person, he's a "COWARD" CONCEALED CARRY CAN'T COME FAST ENOUGH!!!
Joe W. March 23, 2013 at 08:21 PM
A clear example why we need concealed carry now!! Criminals will always have access to guns and completely disregard any laws. It is of utmost importance that law abiding citizens have the ability and the option to defend themselves. Without concealed carry you have no option.
Bluto March 23, 2013 at 08:26 PM
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.
Joe W. March 23, 2013 at 08:26 PM
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.
Joe W. March 23, 2013 at 08:30 PM
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.
Bluto March 23, 2013 at 08:48 PM
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.
Harry Callahan March 23, 2013 at 08:52 PM
Tori you just don't get it,your just many that have become brainwashed,what I say is the truth and you get on your liberal soap box and condem me,you don't think the media is bias well your one dumb buddy and the scary part is there is more of you,to bad I have been around the block more than you.
