The fire left significant damage and forced Shapiro, his family and guests to evacuate the building early Sunday. The man, arrested later in the day, faces charges including attempted homicide, terrorism, aggravated arson and aggravated assault, authorities said.
In court documents, authorities said Cody Balmer told them after he was taken into custody that he would have beaten Shapiro with a hammer if he had found him. Balmer had walked an hour from his home to the governor's residence, documents say.
Shapiro said he, his wife, their four children, two dogs and another family had celebrated the Jewish holiday of Passover at the residence on Saturday and were awakened by state troopers pounding on their doors at about 2 a.m. Sunday. They fled and firefighters extinguished the fire, officials said. No one was injured.
At a Sunday evening news conference in front of the badly damaged south wing of the governor's residence, Pennsylvania State Police Col. Christopher Paris identified the man in custody as Balmer, 38, of Harrisburg.
Police call arson a planned attack
Balmer apparently scaled an iron security fence that stands around 7 feet (2.1 meters) and is monitored by security cameras, police said.
Police became aware someone had climbed over the fence and began a pursuit on the grounds but initially didn't locate anyone.
Police allege Balmer broke into the southern wing of the residence, entering a room often used to entertain crowds and display art, and set a fire using a homemade incendiary device. Police declined to elaborate on the device, but the fire left significant damage to the room, charring walls, tables, buffet serving dishes, plates and a piano. Window panes and brick around doors and windows were blackened.
Balmer was inside for around a minute before he left and escaped the premises, authorities said.
Suspect faces charges
Authorities said Balmer will face charges of attempted murder, terrorism, aggravated arson and aggravated assault.
Balmer has faced criminal charges over the past decade including simple assault, theft and forgery, according to online court records. He drew a sentence of probation after guilty pleas to theft and forgery counts. Simple assault charges from 2023 appeared unresolved.
Authorities did not say whether Balmer has a lawyer or where he was being held. Calls to people believed to be his relatives went unanswered or unreturned on Sunday. One recent residence listed for him in Harrisburg was condemned in 2022.
Attack happened during Passover
The attack happened on the Jewish holiday of Passover, which began at sundown on Saturday.
The holiday commemorates the Israelites’ liberation from slavery in ancient Egypt, including their 40-year journey through the desert. It is one of the holiest days of the year for Jews and is celebrated with a special meal called a Seder, which includes the eating of matzah, a type of unleavened bread, and the retelling of the Exodus story.
Shapiro had celebrated with a Seder at the official residence with his family and members of the Jewish community in the same room where authorities said the fire was set.
