SOLON TOWNSHIP, Mich. (WOOD) — An explosion at a mobile home north of Cedar Springs sent a man living there to the hospital with severe injuries.

It happened around 5:15 p.m. Tuesday at White Creek Country Estates mobile home park off Egner Street NE west of US-131 in Solon Township.

“Loud enough to get me out of chair and out my door, and there was numerous pop, pop, pop after that,” said Dan Boekeloo, a resident at the mobile home park.

The Kent County Sheriff’s Department said it doesn’t yet know what caused the fire, but several butane tanks were found within the carport.

“Don’t know what caused the tanks to explode, but it’s the avenue we’re looking at right now. It’s still a fresh investigation,” Sgt. Joy Matthews with the Kent County Sheriff’s Department said.

The 50-year-old man was pulled away from the carport by neighbors and taken to the hospital.

“He sustained substantial injuries to both of his hands and severe burns on on his body,” Matthews said. “One thing we’re thankful for is the heroism neighbors displayed. A lot of people get scared and freeze during times like this.”

The victim’s mother was inside the home but was not injured. The explosion was so powerful that nearby homes also suffered damage.

“Parts of the gentleman whose place blew up, his shed, is in her (nearby neighbor) front porch,” Boekeloo said. “Definitely damage done.”

A Michigan State Police bomb squad and arson investigators responded to the scene after homemade fireworks were found. It’s unclear if fireworks contributed

The Kent County Sheriff’s Department is actively investigating the explosion.
