A 28-year-old man accused of shooting another man to death in the parking lot of a North Gettysburg Avenue bar in 2011 pleaded guilty Thursday to a bill of information in the case.

D’Angelo Mattison pleaded to felony involuntary manslaughter, which carries a specification that will add three years to any sentence because a firearm was used.

The plea was entered in Montgomery County Common Pleas Court to Judge Barbara P. Gorman.

There was no sentencing date listed in online court records.

Police answering a robbery call just after midnight Saturday, Sept. 10, 2011, heard a barrage of gunfire and responded to PC’s Lounge, 2339 N. Gettysburg Ave. There they found Stephone Cantrell’s body in a bullet-riddled car.

The Montgomery County Coroner’s Office said Cantrell, 43, was shot multiple times and died at the scene Sunday morning.

Hours later, police picked up D’Angelo Mattison, then 25, in the vicinity of the bar. After questioning, he was arrested in the homicide.

At the time, Dayton Sgt. Dan Mauch, head of the homicide unit, declined to say what may have motivated the shooting.

Mattison is being held on charges of murder, felonious assault and tampering with evidence.

A bill of information is a formal written accusation made by a prosecuting attorney. The information can be used instead of an indictment.

In cases of a plea agreement involving a bill of information, a defendant must waive the right to have the case presented to a grand jury and allow it to proceed by indictment.
