Police officers were investigating several stabbings during a hostage situation at a home in Woodland Hills on Sunday, authorities said.
A man hoping to reconcile with his ex-wife came to the house around 8 a.m. with a bouquet of flowers.
The man found his former wife at the home with her new boyfriend and held the pair hostage with a machete, according to investigators.
Both the ex-wife and the boyfriend were slashed with the large knife, before the man turned the weapon on himself, detectives told KTLA.
The ex-wife was able to call 911 for help around 1:30 p.m.
All three were taken to the hospital. Both of the men were in critical condition.
