MINNEAPOLIS — Two people are dead after a dump truck collided with an ambulance in Itasca County.

The crash occurred Tuesday morning in Lawrence Township. According to the Minnesota State Patrol, the ambulance was heading south and the dump truck was heading east when they collided at the intersection of County Roads 336 and 57, WDIO-TV and KMSP-TV reported.

Killed were 51-year-old Troy Boettcher of Warba and 17-year-old Joseph Latimer of Grand Rapids. Both were in the ambulance. State Rep. Spencer Igo of Grand Rapids said Boettcher was an emergency medical technician.

The ambulance driver, a 28-year-old Cohasset woman, suffered life-threatening injuries. The dump truck driver, a 67-year-old man from Nashwauk, also suffered life-threatening injuries.

Minnesota Department of Natural Resources Conservation Officer Sarah Grell was killed in a crash near the same intersection last month.

Igo said safety at the intersection must be improved.
