Carpenter, 21, ran away. Investigators found a stolen gun along his getaway route. Someone tried to “obliterate” the gun’s serial number, police said.

Mitchell, 20, died a short time later at the hospital. 

Carpenter was arrested by U.S. Marshals and members of the Eastern Pennsylvania Task Force around 3:30 p.m. in a home along the 5300 block of Baltimore Avenue.

At one point, Carpenter tried to get away as officials surrounded the southwest Philadelphia home he was in, but eventually surrendered without incident.

Phoenixville Police Chief Thomas Sjostrom called Thursday's shooting an isolated incident and said Carpenter likely didn't pose any threat to the community or schools. As a precaution, local schools kept students indoors for most of Friday.

Friends called Mitchell a funny and goofy guy despite suffering personal tragedy. His older brother was gunned down, also at the age of 20, a few years ago, friends told NBC10.

A vigil was planned for 7 p.m. Friday at Children's Plaza.
