UPDATE: The Marathon County Sheriffs Department says remains have been found in the home that exploded Thursday morning near Pioneer Lane. Patrol Lieutenant Fred Goch says tests are still pending to determine of the charred remains are human. "I don't know the status of what those remains are at this point but an autopsy is in the works." Dental records may be needed to confirm identity.
Investigators also now believe the explosion was intentionally set. Goch says they're still trying to figure out what the devices were. "We'll get a determination of that very soon. We've got investigators on scene. They are working with the state fire marshal's office, and the investigation continues." They say five explosive devices were "chained" together in the basement of the home, and were rigged to go off simultaneously.
43-year-old Jesse Jehn lived alone in the home. His whereabouts have not been confirmed since the blast.

TOWN OF WAUSAU, Wis (WSAU) -- There was a house explosion in the Town of Wausau earlier this morning. It happened just before 7am near the intersection of Pioneer Lane and North 85th Street.
Neighbors heard the explosion and called 911. Sheriff Scott Parks says they were on the scene quickly after the 911 call. "We had a squad relatively close, could see that there was a fireball. They arrived on scene and could see there was substantial fire coming out of the residence." Neighbors reported that the blast rattled their windows and shook their homes. None of the nearby structures were damaged.
The home was engulfed in flames when firefighters arrived. The house is said to be a total loss. All of the outer walls of the house are charred and are no longer standing. Marathon County emergency management director Steve Hagman says crews are still trying to determine if anyone was inside at the time of the explosion.
Parks says they were cautious at the scene because of the explosion. "In the process of the fire and first responding deputies, they noticed devices that were suspicious in nature, so they contacted the Bomb Squad to make sure that everything was safe." But he can't say what the devices are right now. "No not yet, because they used some techniques to disrupt the devices they thought were suspicious, so until we can actually put everything back together, that's when we'll first make determinations."
The State Fire Marshal is on the scene to help in the investigation
It's unclear if there were any injuries. No further information is being released.
