Souderton: Police on Monday surrounded a home outside Philadelphia where they believe a suspect had barricaded himself after shootings at multiple homes.
The man was suspected of killing five people today morning at three different homes, police told WPVI-TV.
The communities are about 6.5 kilometers from each other in Philadelphia's northwestern suburbs.
Officials are referring questions to the district attorney's office, which did not immediately return messages left by The Associated Press.
Police said they believed the suspect was holed up at the Souderton shooting scene.
SWAT teams with armored vehicles and rifles focused on a home on a block of brick-faced houses.
Police Chief Tim Dickinson said officers saw movement in the home but were unsure if it was the suspect.
Several area school districts ordered students and teachers to shelter in place.
