South suburban man charged in Tinley Park shooting death

TINLEY PARK, Ill. (Sun-Times Media Wire) -

Authorities have charged a Markham man in connection with a fatal shooting Thursday after an attempted robbery outside a Tinley Park convenience store.

Police Chief Steven Neubauer said Saturday that Christopher J. Dyson, 18, of Markham, has been charged with murder and armed robbery. Police arrested Dyson following a police chase into Oak Forest and a 45-minute manhunt.

Dyson was scheduled to appear in bond court Saturday, but his bond has not yet been set.

Thomas Mastro, 24, was shot to death Thursday in the parking lot of a Tinley Park 7-Eleven lived just a few blocks away, had a young son and would have been celebrating his 25th birthday Tuesday, his family said.

Dyson allegedly attempted to rob Mastro outside the store, then shot him and left in his vehicle.

An off-duty Tinley Park police officer at a nearby gym was flagged down by a bystander, who pointed out Dyson's vehicle leaving the scene, police said.

That officer chased Dyson's vehicle to 147th and Oak Park Avenue, where dozens of police vehicles from the Tinley Park, Oak Forest, Orland Park and Cook County Sheriff's police departments converged.

"The fact that an off-duty officer in a marked car was at the scene almost immediately was instrumental in the capture of this armed offender," Tinley Park Police Chief Steve Neubauer said in a written statement released Saturday. "The Village's Personal Squad Program is a force multiplier and enhances public safety in our community."

Mastro, of the 6900 block of Coachwood Trail, Tinley Park, died at Palos Community Hospital of a gunshot wound to the chest. On Friday afternoon, as family and friends gathered at the home, his father, Perry Mastro, described Thomas as "a good kid." He was an independent contractor and the father of a 4-year-old son.

The boy "thinks his dad is hurt," Perry Mastro said Friday.

The family declined to specify what type of work Thomas Mastro did as an independent contractor and declined further comment.

"Our thoughts and prayers go out to the victim's family and friends," Tinley Park Mayor Edward Zabrocki said in a written statement. "This is a horrible crime and a tragic loss of life."
