A domestic dispute between a husband and wife ended early Tuesday with the apparent fatal stabbing of the Rancho Palos Verdes man, authorities said.

The wife called police at 1:04 a.m. to report domestic violence at the 5900 block of Flambeau Road, according to a statement release by the Los Angeles County Sheriff's Department.

Lomita deputies arrived at the home the married couple shared with their two young children. The woman came out with her 7-year-old son. Inside, deputies found the man with stab wounds and the couple's unharmed 4-year-old daughter.

The 40-year-old man was pronounced dead at the scene, according to the L.A. County coroner's office. A handgun and a butcher knife were found nearby. The cause of death was unknown.
