CALIFORNIA BRIEFING / LOS ANGELES

A UCLA research assistant seriously burned in a lab fire last month died from her injuries Jan. 16, according to a school spokesman.

The 22-year-old woman, who was not identified, died Friday at Grossman Burn Center in Sherman Oaks, where she was transferred after first being treated at UCLA Medical Center, said spokesman Phil Hampton.

The accident occurred in the school’s molecular sciences building, after chemicals caused a flash fire.

The woman suffered second- and third-degree burns over her upper body, officials said.

The fire is under investigation by UCLA’s Environmental Health Science department, Hampton said.
