Rancho Cucamonga, California — A 54-year-old man lit his mother on fire and then locked himself inside a Southern California home for five hours before surrendering to authorities Monday, officials said.
Deputies responding to a domestic violence incident before dawn found the 73-year-old woman suffering from burns in a Rancho Cucamonga neighborhood, San Bernardino County Sheriff's Department spokeswoman Jodi Miller told reporters.
The woman ran from the house after the alleged attack and got help from a neighbour in the city about 45 miles (72 kilometres) east of Los Angeles, Miller said.
She was hospitalised in critical but stable condition.
The woman, who was not identified, told investigators her son had been acting erratically and set her on fire, though authorities did not say how.
