UPDATE: Tinley Park Man Fatally Shot in Argument in Store Parking Lot

Thomas P. Mastro, 24, died from a gunshot wound to the chest Thursday after an argument in the parking lot of a Tinley 7-Eleven. Police have a man in custody, but charges have not been filed.

One man is in custody Thursday afternoon, in connection with a fatal shooting at a 7-Eleven convenience store in Tinley Park, according to reports.

The shooting happened between two men who got into an argument around 3:05 p.m., in the parking lot of the convenience store at 16658 S. Oak Park Avenue in Tinley Park, said Village of Tinley Park spokesman Jason Freeman.

Thomas P. Mastro, 24, of Tinley Park, died from a gunshot wound to the chest, according to the Cook County Medical Examiner's Office. 

Tinley Park police still have a suspect in custody, but charges have not been filed, police said. The department is working with the Cook County State's Attorney's Office in the continuing investigation, police added.

The suspect fled the scene in his vehicle northbound on Oak Park Avenue and was followed by an off-duty Tinley Park police officer, who was first on the scene, a village press release stated.

After a 45-minute manhunt, he was captured by police at around 147th Street and Central Avenue in Oak Forest. Tinley Park and Oak Forest police also were assisted by officers from Orland Park police and a helicopter from Chicago/Cook County Police Department, the release stated. Cook County Forest Preserve and Palos Park police also were on the scene.

A handgun connected to the shooting was found Thursday north of 159th Street on Oak Park Avenue handgun, Tinley Park police said. 

Residents in a mile radius of the shooting were sent a village alert about the incident, but because the shooter had fled so quickly, there was no immediate danger to residents, the release stated. Community Consolidated School District 146 in Tinley Park did not go into lockdown, because it was not notified of the incident by the time of dismissal at 3:35 p.m.

The manhunt had some streets blocked off and slowed down traffic in the area. At one point, Oak Park Avenue between 143rd and 151st Street was blocked off, as well as 143rd Street east of Harlem Avenue.

Tinley Park police confirmed late Thursday that it is being investigated as a homicide. The victim was pronounced dead at Palos Community Hospital.

Facts are facts! Race has everything to do with a descriptor to help find an offender.

Why would you lockdown the schools? All that does is concentrate the kids in one place. It makes it easier for the criminals to hurt defenseless people, like shooting fish in a barrel. Lockdowns are unsafe.

I've traveled to many stares, mostly out west and down south. I've found people in general more polite and they mind their own business and respect others property. There is less violence also. Could it be that everyone can have a gun, as opposed to here, where only the criminals carry guns around? I think so.

When seconds count... the police are just minutes away.

This is the first I heard of it being over a parking spot. I've heard about five different things now, and I will probably wait until the official reports come out tomorrow.
