The man who firebombed the official residence of Pennsylvania Gov. Josh Shapiro pleaded guilty on Tuesday and was sentenced to 25 to 50 years in prison, prosecutors said.

Cody Balmer pleaded guilty to charges including aggravated arson, arson and the attempted murder of Shapiro, the Dauphin County District Attorney’s Office said.

Balmer allegedly hopped a fence at the governor’s mansion in Harrisburg, broke windows and hurled Molotov cocktails inside he made from beer bottles and gasoline, police said.

The attack occurred in the middle of the night, hours after the Shapiro family hosted more than two dozen people for the first night of Passover. The family was home at the time, but no one was hurt.

Balmer called 911, identified himself and confessed, allegedly telling the dispatcher that Shapiro “needs to know that he ‘will not take part in his plans for what he wants to do to the Palestinian people.'”

Balmer allegedly told police he would have attacked Shapiro with a hammer if he happened upon the governor inside the residence, according to court documents.

Balmer was a mechanic who may have been experiencing financial and mental health problems, sources previously told ABC News.

Balmer, who was arrested at 38 years old, will first be eligible for parole when he is 63, prosecutors said.
