(NewsNation) — New details have emerged about an arson attack on the Pennsylvania governor’s mansion that caused Gov. Josh Shapiro and his family to flee to safety on Sunday.
Court documents outline the suspect’s alleged plan to beat Shapiro with a hammer during the attack, which took place on the first night of Passover.
Arson attack on Gov. Josh Shapiro’s home
Local authorities responded to a fire at the residence around 2 a.m. EDT Sunday. On social media, Shapiro said he woke up to “loud bangs” on the door. The governor, his family and a visiting guest fled to safety from the fire, which authorities deemed to be arson.
Shapiro, 51, decried the violence and said it was inappropriate regardless of the party or individual at which it was directed.
“This kind of violence is becoming far too common in our society,” he said.
New court documents allege the suspect was aware Shapiro could be home and planned to beat him with a hammer if confronted.
Damage to the governor’s mansion
Authorities say the suspect used Molotov cocktails to start the fire, which caused significant damage to the mansion’s south wing.
Images show damage to rooms where Shapiro had hosted a Passover seder hours earlier. Authorities say the suspect scaled a fence and broke into the property before using an incendiary device and evading police when they responded to the emergency.
