A woman was found dead and a man was hospitalized with severe injuries after a Wednesday morning explosion and fire at a home near Lake Vermilion.

The fire was reported around 9:36 a.m. on the 1700 block of Everett Bay Road in Greenwood Township, near Tower, St. Louis County Undersheriff Jason Lukovsky said.

The man was airlifted by Lifelink to Essentia Health-St. Mary's Medical Center in Duluth. The extent of his injuries was unknown Wednesday afternoon, the St. Louis County Sheriff's Office said in a news release.

Remains found in the residence are believed to be from a woman who was inside at the time of the explosion. Identification of both victims are pending next of kin notifications and positive identification by the medical examiner's office.

Although the Minnesota State Fire Marshal’s Office still has to investigate the cause of the explosion and fire once debris from the explosion cools, Lukovsky said authorities believe it was mechanically related and possibly the result of a propane leak.

"We had numerous people call because they heard the blast," he said.

The fire has been extinguished and the home was lost to the explosion and fire. Crews were still on the scene late Wednesday afternoon.

The Greenwood, Breitung Township, Tower and Vermilion Lake Township fire departments responded to the scene, as did Tower and Virginia ambulance services.
