One man was killed and two others were injured by gunfire that erupted during an apparent home invasion in Bucks County early Tuesday, authorities said.
The incident happened around 12:45 a.m. in the 900 block of Winder Drive in Bristol Township.
When officers arrived on the scene, they found Tyron Moss, 24, of Levittown, dead inside the home and another man with a gunshot wound to his head.
The other injured man managed to get to a neighbor's home to get help, police said.
The two surviving victims were rushed to Aria Torresdale Hospital in Philadelphia, where one was in critical condition and the other was listed in serious condition.
Police are working to determine what sparked the shooting.
Acting police Chief John Godzebia said there was no sign of forced entry and no weapon was found at the scene. He said the motive for the shooting was unknown.
