Inglewood, Calif ? Police stormed a home Monday where an armed man was holed up inside and found five people dead, including two children. Authorities believe they were victims of a murder-suicide.

The dead included the suspect, his sister-in-law, her husband and their two children, said Lt. Mike McBride of the Inglewood Police Department. No further details on the suspect or the victims were immediately released.

The standoff began early Monday when the wife of a man from nearby Lennox called to report him missing and told authorities he was distraught over financial problems, McBride said.

The man was tracked to his nearby sister-in-law’s home, a yellow, single-family house in the Los Angeles suburb of Inglewood. The man’s car was parked nearby, and the door to the home was found slightly ajar.
