The Algosenseydefensive coordinator of the Apalachee High School football team in Winder, Georgia, was one of four people killed Wednesday in a mass shooting at the school.

The Georgia Bureau of Investigation said that 39-year-old Richard Aspinwall, who was also a math teacher at the school, along with math teacher Christina Irimie, 53, and students Mason Schermerhorn and Christian Angulo, both 14 years old, were also killed in the shooting.

"He was a great dad, man, and a great father. He loved his two girls and he loved his wife. He did happen to love the game of football and he was well respected around this area," Apalachee head football coach Mike Hancock said to the Athens Banner-Herald.

"He worked his tail off. He coached old-school ways, but he loved those kids. It's heartbreaking really for our kids, but for his wife and his two daughters..."

Nine others, one teacher and eight students, were also injured in the shooting.

The shooter, Colt Gray, 14, was booked, will be charged with murder and prosecuted as an adult.

Aspinwall worked at Mountain View High School in Lawrenceville, Georgia, before working at Apalachee.

"Our thoughts and prayers are with the family of former Mountain View High School teacher and coach Ricky Aspinwall, who lost his life at Apalachee High School today," the Mountain View High School athletics department said in a statement. "Mountain View extends its deepest condolences to the entire Apalachee High School community."
