A 22 year old man from Hillman died Friday night after a large explosion at a home in Wellington Township.
Michigan State Police say the man was loading a wood boiler into an attached garage when the blast killed him.
When troopers arrived they saw three of the four garage walls blown out.
The explosion also critically injured another woman. She was flown to a Saginaw hospital.
Two other females and a 9-month old infant were also in the home. They were treated and released.
The explosion is still under investigation.
