DARBY, Pennsylvania (WPVI) -- A 17-year-old has been charged with first-degree murder in the fatal shooting of a 14-year-old boy in Darby.
Delaware County officials say Shawn Parker of Greensboro, Maryland, is being held without bail for allegedly shooting the unidentified teen.
The incident happened on Wednesday just after 5:30 p.m. in a house on the unit block of South 7th Street.
When officers arrived at the scene they took the victim to Penn Presbyterian Hospital, where he was pronounced dead.
According to official reports, Parker and the victim had a history of disagreements between them.
"It's not over drugs, it's not over things like that. It's just sometimes a dispute over social media or in the neighborhood," noted Delaware County District Attorney Jack Stollsteimer.
Allegedly, Parker was waiting for the victim in the home. When the teen walked inside, police say Parker pulled a gun and opened fire on him.
"One of them had a beef with the other, so the 17-year-old pulled out a gun, fired multiple times killing the 14-year-old, and as he was laying on the ground, the 17-year-old came over and continued to shoot," said Stollsteimer.
Police say the victim was shot 21 times.
Witnesses say Parker fled from the scene.
Through quick police work and the coordination between law enforcement agencies, police say he was caught in just 15 minutes.
Officials are not sure where he got his firearm.
Court documents say the victim also had a gun, and fired it once before he collapsed.
"It's absolutely horrendous what's going on. We have to do something as a society, we have to address why these young people are killing each other and why they have access to deadly weapons to do so," Stollsteimer said.
Parker was arraigned and is scheduled for a preliminary hearing on April 19.
Officials have not released the victim's identity.
