PITTSBURG — No one was injured during a blaze in Pittsburg Friday night that engulfed a duplex on John F. Kennedy Street, according to a captain with the Pittsburg Fire Department.

Capt. Terry Lucchi said the department was dispatched at 10:56 p.m. when a passerby saw the fire. The cause of the fire is undetermined, he said, but started at 2003 John F Kennedy Street.

That apartment “sustained heavy fire” and the neighboring residents at 2001 John F Kennedy has smoke and water damage. Both apartment were occupied when the fire started, he said.

The captain was unsure if either renter has insurance. American Red Cross gave assistance to the residents at 2003 John F Kennedy Street.

Neighbors said flames engulfed the duplex and looked on as firefighters put out the flames during temperatures in the low teens. Anna Hall said she was sleeping in her apartment across the street when she was woken by sirens.

“The flames were extremely high,” she said.
