SALT LAKE CITY (AP) — A retired Utah sheriff's deputy has died following a small airplane crash that critically injured him and killed another man.

Jason Sorensen died Monday as a result of injuries sustained in the accident near Centerville Thursday, KUTV-TV reports.

Sorensen was a lieutenant with the Davis County Sheriff’s Office, which he served as a paramedic and pilot for Intermountain Life Flight.

Authorities do not yet know the cause of the accident that also killed 72-year-old Andre Kostrzewa of Salt Lake.

Kostrzewa died at the scene and Sorensen was transported with critical injuries and burns to a hospital, where he later died.

“Davis County Sheriff’s Office is hurting today,” Sheriff Kelly Sparks said in a statement. “Jason was universally loved. He had a huge impact on the lives of many people in Davis County and around the state.”
