FAIRPLAIN TOWNSHIP, Mich. (WOOD) — Two people were found dead following a house fire southeast of Greenville Thursday morning, police say.

The fire broke out in the rural 4200 block of West Fenwick Road west of Grow Road in Fairplain Township, Michigan State Police said. Firefighters were called there shortly before 8 a.m. and found two homes on the same property on fire, including one that was fully involved.

“Coming down Fenwick Road, it was just a big ball of fire when we got here,” Sheridan Fire Chief Ed Lingeman told The Daily News of Greenville.

He called in three other departments to help douse the flames. They focused on trying to save the second house, which was showing fewer flames when they arrived. He said the flames likely spread from the larger home to the smaller.

The larger two-story house burned to the ground. The other sustained enough damage that it is likely a total loss, Lingeman told The Daily News.

Two bodies were discovered in the first house, one shortly after the fire was out and the second several hours later.

Authorities are still working to identify the dead. The Daily News reports the property belongs to William and Sara Wyckoff.

MSP said the fire is being investigated as suspicious. It’s not yet known what started it.
