According to a criminal complaint, the incidents began Wednesday at a home on Revo Road in Baldwin Borough.
Court documents filed against Philip and Paul Chalmers, both 49, of Baldwin, said the pair attacked and threatened to kill paramedics who were trying to help their father who was in respiratory distress following a medical emergency.
Five paramedics told police the brothers attacked them and claimed they weren’t doing enough to help their father.
Their father was rushed to the hospital, where he died, and court documents allege that upon hearing the news, the brothers went outside, picked up a traffic cone and threw it through the window of a Baldwin ambulance.
The brothers are facing several charges including aggravated assault and obstructing emergency services.
Police said on Thursday a third brother, Vincent Chalmers, 46, set the family home on fire.
Chalmers was taken into custody by Pennsylvania State Police in Meadville, where he is being lodged locally awaiting extradition to Allegheny County to face arson charges.
The owner of the Revo Road home, who also lives nearby, said he saw Chalmers pouring gasoline around the house and then saw flames.
