UPDATE: Fallen Philly Firefighter is First Female to be Killed in the Line of Duty

A Philadelphia firefighter was killed battling a blaze overnight in the city’s West Oak Lawn section.

Joyce Craig Lewis, an 11-year veteran of the Philadelphia Fire Department, is the city’s first female firefighter to die in the line of duty, The Philadelphia Inquirer said.

The fire broke out around 2:50 a.m. Tuesday, Dec. 9, in the basement of a home on the 1600 block of Middleton Street, 6ABC said.

Craig Lewis, 36, was from Engine 64, NBC Philadelphia said. A black bunting was hung over the fire engine’s door on Tuesday morning, the Inquirer said.

“Our thoughts and prayers go out to the family of this firefighter who made the ultimate sacrifice,” Philadelphia Mayor Michael Nutter said, according to the Inquirer. “This firefighter was doing her job to the best of her abilities, but unfortunately died fighting this fire.”

Craig Lewis was the mother of a teenage son and a 16-month-old daughter, 6ABC said. She was one of only 50 women who serve in the Philadelphia Fire Department, NBC said.

The fire remains under investigation.
