GARDEN GROVE (CBSLA) — The Garden Grove home where one person was killed and two others were injured in a fire did not have working smoke alarms, fire officials said Monday.

Firefighters were called out to a home in the 13000 block of Jefferson Street at about 8 p.m. Sunday on the report of a fire. At the scene, they were told as many as three people were trapped on the second floor, so firefighters immediately began searching the home, while working to keep the fire confined to one upstairs bedroom.

Another person who suffered minor injuries while exiting the house was taken to a hospital.

The cause of the fire is under investigation. Firefighters say smoke alarms were not present and/or working inside the home.
