HILO » The trial of a 73-year-old Big Island man on an attempted murder charge ended after he agreed to plead guilty to lesser charges.

Joseph Amormino Sr., pleaded guilty Thursday to felony assault, use of a firearm in the commission of a felony and two counts of terroristic threatening. Prosecutors agreed to seek a maximum sentence of 25 years.

Amormino is a retired Hawaii Community Correctional Center guard.

The Hawaii Tribune-Herald reports he shot a 57-year-old June Shirshac four times on Mother’s Day 2012 after she had broken off her relationship with him. The shooting was preceded by a road rage incident in which Amormino used a gun to threaten three people.

Shirshac was shot in both legs, her hand and her shoulder.

Sentencing is scheduled for Nov. 21.
