Police Chief Eric Merkel said surveillance recordings from inside the store where a city teen was wounded Sunday night provided investigators with a "crisp and clear" picture that helped them identify the teenage boy they arrested Tuesday.
After an arrest warrant was issued earlier in the day, 16-year-old Christopher Jackson of 151 Miller St. S.W. turned himself in to police.
He is charged with felonious assault and aggravated robbery. He was being held at the Trumbull County Juvenile Justice Center in Warren.
Police said Jackson shot Shane Stein, 17, in the elbow about 7:45 p.m. Sunday evening outside Atlantic Beverages at 208 Atlantic Street N.E. Stein was treated for his injury at Trumbull Memorial Hospital.
Meanwhile, a person taken into police custody in relation to a separate shooting Monday evening at the same Warren location, was released without being charged.
That shooting about 9:30 p.m. Monday in the Atlantic Beverages parking lot left Khaled Nassar, 22, dead.
Police had taken the man, whose identity has not been released, into custody after a brief pursuit Tuesday, calling him a person of interest.
Merkel said when police tried to talk to the man, he fled in a vehicle and a brief police chase ensued.
The pursuit ended in the Karl Street area when he exited the vehicle and was chased down and bitten by a police K9 dog. The man was taken to a nearby hospital.
Several people claiming to be the man's relatives, including one woman who identified herself as his aunt but asked that her name not be published, called the Tribune Chronicle newsroom Wednesday to report he had been treated for a dog bite to his arm, questioned by police on Tuesday and released the same night.
Police confirmed he had been questioned and released. Officers have not said how the man may be connected to the shooting. They said they were not releasing the individual's name because he was not charged.
Warren Police Lt. Jeff Cole said the investigation into Nassar's death is ongoing and that police were gathering evidence.
Recordings of the 911 calls from Monday reporting the shooting, released Wednesday, indicate several callers reported the incident. One female caller told a dispatcher that there was another gunshot at the same store.
"The the guy that shot my brother last night on the corner of Vine and Atlantic," the caller said.
A male caller said "Um, the guy who got shot came up to Atlantic Beverage."
The dispatcher asked "Another shooting?"
He said "Yeah, and they stole his vehicle."
Nassar's death marks Warren's 10th homicide of 2013.
