A northern Cambria County businessman died in a fire Tues­day at his home, Cambria County Coroner Dennis Kwiatkowski said. James Paul Tirpak, 55, of 2221 St. Lawrence Road, Patton, was found dead after firefighters got the blaze under control, Kwiat­kowski said. Tirpak and his wife owned Hubcaps Grill, located near Cambria Heights High School. About 2:25 p.m., a caller to the Cambria County 911 Center reported that flames were through the roof, and he wasn’t sure whether anyone was inside the residence, Chief Patrick Wood of Patton Fire Company No. 1 said. The home was fully in­volved in fire when the first Patton units arrived. Tirpak was pronounced dead at the scene at 5:20 p.m., Kwiat­kow­ski said. He was found in a rear bedroom of the one-story house. Tirpak’s wife wasn’t home at the time of the fire. The cause of Tirpak’s death is undetermined, pending an autopsy that is scheduled for today at Mem­orial Medical Center, Johns­town, Kwiatkowski said.
