FRAZEE, Minn. — Authorities have identified the elderly man from Frazee who died after suffering severe burns from a grass fire on Wednesday, May 3.

According to the Becker County Sheriff's Office, Alvin George Schwarzrock, 80, died from injuries sustained in the fire.

Frazee Fire reported a swamp on fire at 5:43 p.m. Wednesday at 13290 440th Avenue, in Evergreen Township, northeast of Frazee.

A press release from the Becker County Sheriff's Office says the reporting firefighter observed a male coming from the area of the fire with what was believed to be 3rd-degree burns and asked for fire departments and rescue services.

Before emergency personnel could arrive, the burn victim was taken to the Perham Hospital by a private vehicle, where he was first treated and then taken to Regions Hospital in St. Paul. The Becker County Sheriff's Office learned Thursday, May 4, that Schwarzrock died.

Frazee Fire Department Chief Nathan Matejka said firefighters were on the scene for about two hours, along with the Wolf Lake Fire Department, MN DNR Forestry, Frazee Police Department, MN Fire Marshal's Office, Essentia-St. Mary's EMS, and LifeLink Air Ambulance.

The incident remains under investigation.

According to the Minnesota DNR , most of the state is considered to be under a "high fire danger" alert, which means fires can start and spread very quickly.
