A 27-year-old woman died Friday after pouring gasoline on herself and igniting it during a fight with her boyfriend, San Bernardino authorities said Tuesday.

Sonnealita Louder was pronounced dead Friday in the 3500 block of East 21st Street in San Bernardino. She suffered second- and third-degree burns over 90% of her body, said Jason Serrano, a spokesman for the San Bernardino Fire Department.

Police responded to a 2:30 p.m. call Friday about a domestic altercation between Louder and her 44-year-old live-in boyfriend, said Lt. Jarrod Burguan of the San Bernardino Police Department.

Louder became angry, witnesses told police, and “went into the garage of the residence and poured gasoline on herself and set herself on fire,” Burguan said.
