LOS ANGELES (CBSLA) — A man has died and a woman continues to fight for her life after being pulled out of a fire burning at a home in Exposition Park.

The fire broke out at about 12:45 a.m. at a home on Leighton Avenue near Budlong. The flames left the front of the home totally burned out.

A man in his 60s and a woman in her 50s had to be rescued from the burning home and were rushed to the hospital, where the man died. The woman, his sister, remains in grave condition. An engineer who assisted with the rescue was also hospitalized for smoke inhalation, but he is expected to be OK.

It took a half hour for 53 firefighters to put out the flames.

The home was initially reported to be a board-and-care facility for mental health patients. However, it appears the owner of the two-story homes was renting out its rooms. Sixteen people, including four children, were inside when the fire broke out.
