WAUSAU, WI (AP) -

The person found dead after a town of Wausau home exploded is believed to be the owner.

According to a sheriff's department news release, investigators found who they  believe to be 43-year-old Jesse Jehn beneath rubble Friday. It was a day after an explosion almost instantly leveled the one-story house.

Positive identification has not been established.

Marathon County Sheriff Scott Parks told the Daily Herald Media investigators found five explosive devices, including two in separate vehicles outside, one in a nearby storage building and one in a camper.

Detective Jim Armstrong says the devices were connected by timed fuses throughout the property.  He says he believes the explosion was deliberate.

Armstrong says the motive isn't clear, but authorities have responded to the home previously.
