The L.A. County Sheriff's Department today provided new details on the three people who were burned while protecting their homes Saturday in Big Tujunga Canyon.

Two of the people injured refused a mandatory evacuation order, said Sheriff’s Department spokesman Steve Whitmore. He said that the two didn’t realize how serious the threat of the fire was, and that they thought they could protect themselves by jumping into a Jacuzzi.

But when the 80-to-100-foot flames came barreling through their neighborhood, they were seriously burned, said Whitmore.

They managed to get themselves help, he said, and the county sent in a helicopter and airlifted them to a hospital.
