Authorities are seeking a motive in the fatal shooting of four people at a house in Sacramento, Calif.
A police spokeswoman says officers who responded to reports of gunfire at the home Saturday night found three men and one woman dead. She says a fifth person, whom investigators identify as a suspect, was wounded, apparently by someone in the home who confronted him.
Police say the suspect is in critical but stable condition. Investigators aren't sure if there are additional suspects.
Police initially described the killings as occurring during a home invasion, but now say investigators don't know the motive. Authorities have determined that some gang members may have been involved and the attack doesn't seem like it was random.
The names of the victims have not been released. Two were residents of the home and two were what police describe as "guests."
