Los Angeles police and robbery homicide detectives investigate the shooting scene where four people were shot and killed in Northridge, California early December 2, 2012.

Four people were left dead outside a suburban Los Angeles home early Sunday morning, leaving police absolutely clueless as to who is responsible and what their motive was. The single-family house outside which the gunshot victims were discovered had been used as a boarding house—a setup which Los Angeles Police Department spokeswoman Terri Brinkmeyer said she’s not sure was legal. No weapon was found near the scene of the crime and homicide detectives on the case could not identify the victims.
