YOUNGSVILLE — No cause has been determined for the blaze that broke out Sunday and destroyed Lonnie’s Pizza located at 114 E. Main St.

The fire started on the first floor of the two-story building, Youngsville Volunteer Fire Chief Vern Edmisten said.

The call came in around 7:15 p.m. By 9:30 p.m., the fire was largely under control though crews were on scene until nearly 1:15 a.m. and were dispatched back to the scene shortly after 7:30 a.m. Monday morning.

“It (the fire) worked its way through the whole building,” Edmisten added. “Then the building collapsed.”

The chief said that an excavator had to be used to pull the building away, so the fire could be extinguished. On Monday morning, the chief noted, the fire rekindled in a small corner by the street, so the excavator had to be brought back to the scene to tear down the rest of the building.

“It (the building) was a total loss,” Edmisten said.

Fire crews ran multiple water lines to the fire on Sunday evening, including one directly from the Brokenstraw Creek.

Two aerial apparatus – one from Starbrick and the other from the City of Warren – poured a near continuous stream of water on the structure.

Many agencies responded including Youngsville, Sugar Grove, Starbrick, Garland, Spring Creek and Pleasant as well as the county’s Department of Public Safety. The Red Cross, Pennsylvania State Police and Youngsville Police were on scene, as well.

Garland and Youngsville were the agencies that responded back to the scene Monday morning.
