The Los Angeles County Sheriff’s Department is investigating the death of a woman whose body was found inside a Palmdale home where her son barricaded himself Saturday morning.

Sheriff’s deputies responded to the 4300 block of Desert Aire Avenue around 6:15 a.m. for a report of an assault with a deadly weapon. A 74-year-old man had called 911 to report that his stepson had attacked him and his wife, the suspect’s 69-year-old mother.

The body of the woman was located at the home just before 7 a.m.

The suspect then barricaded himself in the garage of the home, LASD officials said.

A sheriff’s SWAT team responded to the scene and set up a perimeter around the home. Neighboring houses were evacuated as part of the law enforcement investigation.

The man, who authorities say is 36 years old, was eventually taken into custody by law enforcement and neighbors were allowed to return to their homes. A 38-year-old woman was also detained as part of the investigation. the Sheriff’s Department said.

Anyone with information about this crime is urged to contact the Los Angeles County Sheriff’s Department’s Homicide Bureau at 323-890-5500. You can also submit an anonymous tip online.
