HIXTON, WI (WTAQ) - A west central Wisconsin man is being held on suspicion of killing his father.
20-year-old Lars Helgeson of rural Hixton was arrested Wednesday night, about the same time that searchers found the body of a man believed to be Brian Helgeson.
Jackson County Sheriff Duane Waldera told reporters Thursday that the body was in such bad shape that they could not confirm who it was, or how he died.
Authorities were hoping those questions would be answered in an autopsy scheduled for Thursday in Madison.
Waldera said the body was apparently buried for 10 or 11 days before a K-9 search team found it. State and local officers took part in the search. They were still gathering evidence Thursday.
Waldera said a motive has not been established.
Deputies started to investigate on Monday, when Lars Helgeson's brother got concerned over suspicious activity. The sheriff said a tip led his officers to a stolen vehicle near Brian Helgeson's house on Wednesday -- and they reportedly saw Lars run away as they approached.
He was later taken into custody without incident.
Waldera says Lars is cooperating with investigators while awaiting court action. He's being held on a possible charge of first-degree intentional homicide.
