Michael Mantenuto — known for his role as hockey player Jack O'Callahan in Disney's Miracle — died on Monday. He was 35.
His death was officially ruled a suicide, PEOPLE reported, citing the King County medical examiner’s office in Seattle, Washington. Mantenuto sustained a self-inflicted gunshot wound.
"Those of you that knew Mike will remember him for his passionate love for his family and his commitment to the health of the force," U.S. Army Col. Guillaume Beaurpere wrote in a Facebook post on Wednesday announcing his death. Mantenuto, a former college hockey player, served in Beaurpere's unit when he enlisted in the Army after his acting career.
Mantenuto appeared alongside Kurt Russell in Miracle, the 2004 movie based on the U.S. men's hockey team's victory over the Soviet Union in the 1980 Olympics.
He is survived by his wife, Kati Vienneau, and two children, Ava and Leo, according to his obituary on Legacy.com.
