Bart Halderson, 50, and his wife Krista Halderson, 53, have been missing since before the 4th of July holiday. Their son, 23-year-old Chandler Halderson, reported them missing after they didn’t return from what he said was a planned weekend trip to their cabin in Langlade County. Chandler Halderson has since been arrested on suspicion of providing a false report in a kidnapping investigation. Investigators found human remains and a bloody tarp in a wooded area in a remote part of Dane County. An autopsy confirmed that father Bart Halderson died from homicidal violence including firearm injury. Krista Halderson is still missing. Chandler Halderson has not yet been charged with murder in his father’s death. A judge ordered him held on a $10,000 bond for the false report charge, despite the prosecutor’s request for a $1 million bond.
