Did arson suspect set 55 other blazes?

Alisha Jackson allegedly got a little hot under the collar when she was spotted by a Philadelphia police detective earlier this week.

Jackson, 30, was on the lam, wanted for torching a car at 52nd and Race streets on Dec. 22, said Lt. John Walker, of Southwest Detectives.

Detective Robert Conway saw Jackson on Farson Street near Ogden, in West Philadelphia, about 11 a.m. Monday. When Conway tried to arrest Jackson, she pepper-sprayed him in his face, Walker said.

Jackson — who was carrying three lighters and a pack of matches — was arrested and now is a suspect in a much larger investigation.

Walker said police are trying to determine if Jackson, of Roosevelt Boulevard near F Street, was behind some 55 car fires set between June 12 and Feb. 9 in West Philly. The arsons occurred in an area between 50th and 55th streets, from Baltimore Avenue to Girard Avenue.

“Someone used a match or lighter to light an accelerant on the exterior of the vehicles, near the grilles or bumpers,” Walker said. “The fires caused tens of thousands of dollars in damages.”

Southwest Detectives are working with the District Attorney’s Office and the Bureau of Alcohol, Tobacco Firearms and Explosives to determine if Jackson was behind the other blazes.

Jackson is being held at the Riverside Correctional Facility on charges that include arson, causing a catastrophe and aggravated assault, court records show.
