Cambria County District Attorney Kelly Callihan, who went to the scene immediately following the explosion, referred questions to state police.
Two victims transported to the Altoona Regional Health System – one male adult and one male teenager – were not identified and the extent of their injuries was not immediately known.
“Right now, we’re still trying to verify the locations of each of our victims whenever the blast actually occurred,” Matchik said.
Neighbors of the Shaners said the family had three children and two are believed to have just been picked up by their bus headed to class in the Cambria Heights School District. Classes were delayed by two hours due to winter road conditions.
The site of the explosion is directly across from the Clearfield Township Municipal Building, which apparently was not impacted.
State police cruisers sat at the entrance to Kepshire Road keeping the curious and the reporters away from the scene, which was about 150 yards from Route 36. Unmarked police vehicles maintained a perimeter near the Route 36 and Kepshire intersection to keep people from crossing through adjacent fields.
A computer rending of the area prior to the explosion shows a house and two buildings, including a garage and a swimming pool. An aerial view after the blast shows a garage and a badly burned vehicle just off Kepshire Road and in the area where the house had been.
“We are treating this as a criminal investigation at this point,” Matchik said. “We want to make sure we conduct this investigation very methodically.”
Hours after the blast, debris such as building materials and paper was spotted hundreds of yards from the scene.
Tufts of fiberglass insulation, carried by Tuesday’s strong winds, dotted the neighboring fields and homeowners’ yards in all directions.
Matchik said Kepshire Road could continue to be closed today, although that was speculative, given the current state of the investigation.
Bradley Kollar and his father were taken into custody March 6, 2012, after a massive raid on a family-owned 47-acre property – the former Rich Mines site – located in Susquehanna and Elder townships.
Stolen equipment, including a front-end loader, was recovered.
Also found were what police described as materials possibly used in a meth lab and some explosive materials.
Court records list John Kollar’s address as Murphy Springs Road in Susquehanna Township.
Both men posted bail and were out of prison at the time.
Bradley Kollar’s mental status apparently had been a concern for authorities for some time.
Court records show that the district attorney’s office, after receiving reports that he was contemplating suicide and may have access to explosives, attempted unsuccessfully to have his bail revoked.
