The Los Angeles Police Department’s West Bureau detective division is investigating the fire, said LAPD officer Liliana Preciado. No other injuries were reported.

The victim’s boyfriend was named a person of interest in the investigation, according to Aareon Jefferson with the Police Department.

The UCLA Daily Bruin described the deceased as a fourth year student who was studying psychology and Spanish. The identity of the woman was not immediately released.
