A Costa Mesa woman died Thursday morning after she intentionally set fire to her mattress and barricaded herself inside her apartment, officials said.
Firefighters found 36-year-old Donna Michelle Sansevero lying unconscious in the bathroom of her second-story apartment at the Park Mesa Villas.
Sansevero was taken to Hoag Memorial Hospital Presbyterian in Newport Beach, where she was pronounced dead. The cause of death was smoke inhalation, officials said.
The blaze did not spread to adjoining units in the large apartment complex, and no one else was hurt.
A maintenance worker at the apartment complex in the 500 block of Paularino Avenue saw smoke coming from the apartment at 9 a.m. on Thursday. When firefighters arrived and tried to enter the apartment, they found the door blocked.
