Prosecutors said surveillance video and property left at the scene helped investigators identify the accused gunman.
GLENOLDEN, Pa. — A 21-year-old man surrendered to police Monday after authorities accused him of opening fire during a dispute inside a Delaware County Walmart, sending a bullet through a glass door and striking an employee outside the store.
Armani Tyrell Waite faces attempted murder and other charges stemming from the July 31 shooting at the Walmart on North MacDade Boulevard. Darby Township police said Waite turned himself in Aug. 3, ending a search that began after he allegedly fled the store on foot. He was arraigned Monday, and a preliminary hearing was scheduled for Aug. 11.
Delaware County District Attorney Tanner Rouse said Waite and another customer had a brief verbal dispute near the store’s self-checkout area shortly before the gunfire. According to the prosecutor, the other customer lifted his shirt and displayed a handgun tucked into his waistband. Waite then allegedly drew his own gun and fired three times.
Authorities said one round passed through a glass door near the store’s entrance and struck a female Walmart employee in the calf while she was outside. She was taken to Penn Presbyterian Medical Center with injuries that were not considered life-threatening. Police said she was released from the hospital the same night and was recovering.
The employee was not involved in the argument, investigators said. Her name has not been released, and officials have not publicly identified the other customer. Authorities also have not announced charges against that man or provided a fuller explanation of what caused the dispute.
Rouse said the available evidence did not indicate that Waite was facing an immediate threat or acting in self-defense when he allegedly fired. The district attorney described the shooting as an incident that could have caused far more injuries inside the crowded store. The allegations against Waite have not been proven in court.
Investigators said surveillance cameras inside the Walmart recorded the confrontation and shooting. Authorities also recovered a handgun and car keys that Waite allegedly left behind. The keys helped police connect him to a vehicle at the shopping center and identify him as a suspect, according to the district attorney.
The shooting prompted customers and employees to seek safety as officers from several Delaware County police departments responded. Police cleared the Walmart and checked nearby businesses while searching for the gunman. Authorities later said there was no continuing threat at the shopping center.
Before Waite surrendered, police obtained an arrest warrant and warned that he should be considered armed and dangerous. He was wanted on charges that included attempted murder, aggravated assault, reckless endangerment and weapons offenses. The exact counts and the full charging documents were not immediately available in the reports reviewed.
Walmart said the safety of its employees and customers remained a priority. The company thanked first responders for their response and said it was cooperating with investigators. The store’s operating status following the shooting was not immediately clear.
The case now moves into Delaware County’s court system. Waite is presumed innocent unless convicted, and prosecutors will be required to present evidence supporting the charges during future proceedings.
