Investigators have determined that a three-alarm fire that injured six firefighters, one critically, in San Francisco's Portola District on Feb.
5 was set intentionally.
The fire was reported shortly before 12:30 a.m. that day at a vacant two-story home at 327 Felton St.
About 10 to 12 minutes after the first team of firefighters entered the home, the roof collapsed, sending hot gas and smoke down a
hallway toward them.
Six firefighters were injured, including Lt. James App, an eight-year veteran of the department who suffered second- and third-degree
burns, and Christopher Posey, an 11-year veteran who was left hospitalized in critical condition.
Fire Lt. Mindy Talmadge said in a news release Thursday that the fire department's arson task force has determined the blaze was set on purpose.
Anyone with information on the fire is urged to call the arson task force's anonymous tip line at 415-920-2944.
