CONNOQUENESSING — A 29-year-old woman is suspected of intentionally setting fire to a mobile home where she lived with her boyfriend, his mother and his son.

Jolene L. Schirra will face arson and other charges in the fire early Thursday morning that destroyed the home in the 1200 block of Route 68 in Connoquenessing, state police said.

Schirra’s boyfriend, Robert Gongloff Sr., 50, was flown to a Pittsburgh hospital for smoke inhalation after he rushed back into the house apparently fearing his girlfriend had not gotten out.

Schirra, however, was safe and sitting in a car in the home’s driveway.

Trooper DuWayne Baird, a deputy fire marshal, said he believes the suspect likely watched Gongloff go into the flame-engulfed trailer home looking for her.

“From where the car was in the driveway,” Baird said, “she could have seen it.”

Baird declined to discuss a motive but he said that Schirra and Gongloff had gotten into an argument a short time before the fire, which started in their bedroom at the back of the trailer.

Police also suspect Schirra was possibly impaired by drugs when she allegedly set the fire.

Gongloff’s condition was not known this morning but he was “doing well,” Baird said. His mother, Janet Gongloff, and his 26-year-old son, Robert Gongloff Jr., were not injured.

Schirra also was unharmed in the fire but several hours later she ended up at Butler Memorial Hospital for a mental health evaluation, police said.

At the hospital, she tried to bite and punch two troopers and spit at them, according to court documents.

Police that afternoon charged Schirra with felony and misdemeanor assault in connection with the fracas at the hospital.

The fire at the trailer home started shortly before 4 a.m., authorities said. Janet Gongloff owns the trailer.

Robert Gongloff, speaking to troopers at Mercy Hospital, recounted that he and his girlfriend had been arguing when he left their bedroom to go to the bathroom.

“He then heard his son yelling, ‘Fire,’” Baird said.

Gongloff Jr. told investigators that he was in the living room when he saw “flickering” coming from his father’s bedroom.

“He got up and saw fire on the mattress and (Schirra) was standing there,” Baird said.

The occupants left the home.

Volunteer firefighters from three departments were called and put out the blaze but the trailer was gutted.

A medical helicopter later flew Gongloff to the hospital. About 7 a.m., troopers led Schirra to an ambulance. But while being placed inside, police said, she became combative with troopers.

She eventually was taken to BMH, where she again allegedly tussled with two other troopers. During the struggle, Trooper Brian Knirnschild injured his right thumb.

District Judge Kevin O’Donnell signed an arrest warrant for Schirra on two counts each of aggravated assault, simple assault and harassment, and an additional charge of disorderly conduct.

Baird said he would soon file separate arson and related charges against the defendant. He would not discuss evidence that indicated the fire was intentionally set.
