A man died and a woman was seriously injured after they were attacked by their daughter's ex-husband on Friday in Inglewood, police said.
Officers responded to a home in the 3700 block of 106th Street around 12:45 p.m., Inglewood Police Lt. Jacqueline Layne said.
Family members told KTLA the suspect went to the house to confront the victims, and hid when officers arrived.
Police identified the suspect as 33-year-old Edward Fernando Ruiz.
After officers left the scene, Ruiz allegedly returned and launched a deadly attack, a family member said.
The male victim was declared dead at the scene, while the woman was transported to the Harbor-UCLA Medical Center in serious condition, according to Layne.
The daughter also suffered injuries in the attack and was hospitalized, family members told KTLA.
Authorities did not immediately know what kind of weapon was used in the deadly attack.
After police arrived on scene, Ruiz got onto the home's rooftop and barricaded himself, Layne said.
He eventually descended after SWAT and hostage negotiators responded and was taken into custody, officers said.
Police have identified Ruiz as the daughter's husband, but family members told KTLA he was her former fiancé.
Family members also said Ruiz was recently released from prison and said the daughter had a restraining order against him.
No further details were immediately available.
