Suspect wanted for burning of victim.

SAN FRANCISCO -- A woman was in critical condition after being severely burned in the city's Bayview District on Sunday afternoon by a man she dated, police said.

Police responded about 12:15 p.m. to the intersection of Hollister Avenue and Jennings Street for a report of a woman screaming, said Officer Carlos Manfredi.

When officers arrived, they found a woman in her 20s who had been severely burned, Manfredi said.

A preliminary investigation revealed that a suspect, who police identified as Dexter Oliver, 22, threw an ignitable liquid onto her, then set her on fire, Manfredi said.

The woman was transported to St. Francis Hospital's Burn Center to be treated for life-threatening injuries, police said.

Police say Oliver and victim were dating and that Oliver is facing attempted murder and arson charges.

Police describe Oliver as a black man, 5 feet 10 inches tall and weighing 155 pounds. He was last seen wearing a red-and-white hoodie jacket, dark pajama pants with a multicolored shamrock print, with gray and red Nike tennis shoes. Oliver also has a design haircut of a fish on one side of his head, and a lighting bolt on the other side.

No motive has been released, and the incident remained under investigation late Sunday afternoon.

Anyone with information about the case is asked to call San Francisco police at 415-929-9446.
