TOWN OF NEWARK, Wis. -

State and county fire investigators were at a burned home Wednesday trying to find more information about how the fire started.

Officials are calling the fire suspicious and are looking for the homeowner’s red pickup truck.

Officials identified the man found inside the home as 62-year-old Thomas MacGowan, of the town of Newark. An autopsy revealed MacGowan died from injuries sustained in the fire.

Crews sifted through debris around and inside the home Wednesday morning. One official removed pieces from the basement and set them aside.

Neighbors said the house fire shocked them.

“The whole half of the house is gone,” Alex Slove said. “It’s quite the sight over there. There’s just burnt studs up out of the ground now, and I’m not used to seeing that.”

Rock County Sheriff’s Office Capt. Todd Christiansen said the fire started around 6 a.m. Tuesday, and the home was fully engulfed when crews got to the scene.

As crews were fighting the fire, they found Macgowan's body in the basement.

Christiansen said there was a shed fire on the property Nov. 11. The cause of that fire was never determined.

“It’s just really shocking that there was a small fire, and then all of a sudden a week goes by and the house is gone,” Slove said. “It’s just kind of surprising.”

Officials are looking for the homeowner’s 1997 red Chevrolet S10 extended cab pickup truck with license plate KY5-599. Anyone with information about its whereabouts should call the Rock County 911 Communications Center at 608-757-2244.
