Three people were shot and killed inside a Kensington home in Philadelphia early this morning, and a fourth was shot outside before the suspected shooter was arrested, according to police at the scene.
Police say events began about 3:45 a.m. at the rowhome on the 600 block of Westmoreland Street.
Multiple people called 911 after apparently hearing gunfire.
When police arrived, the suspected shooter barricaded himself inside the home for little more than an hour. He surrendered to police shortly after 5 a.m.
Detectives said the dead included the suspect's brother, the brother's girlfriend, and an unrelated man who lived at the home.
The fourth person shot, who was found about a block away, was being treated for non-life threatening injuries at Temple University Hospital.
The violence comes on the heels of the shooting death of 4-year-old girl Saturday afternoon in Kensington. Police initially said she was shot by her 5-year-old brother, but Sunday afternoon said the girl's father confessed to the accidental shooting. He initially fled the scene.
