ADAMS COUNTY (WKOW) -- The Adams County District Attorney has filed charges against a man in connection with the death of missing Dane County woman.
Annastasia Evans' body was found by a hunter in a wooded area of Adams County Nov. 23. She was last seen in May.
Thursday, Robert J. Olson, 25, was charged with hiding a corpse, providing false information on a missing person and obstructing an officer.
According to the criminal complaint, Evans' boyfriend and a friend reported her missing in May. In June, the friend told detectives she thought "Bobby Olson" was the last person to see Evans, taking her to Wisconsin Dells on May 4, but coming back without her.
When detectives followed up on Olson, they found he was an inmate in the Dane County Jail. According to the criminal complaint, Olson told police he dropped Evans off at an intersection in Madison to buy heroin and that was the last time he saw her.
But the criminal complaint alleges detectives later found some incriminating texts between Olson and others. It also states Olson told fellow inmates he had been in Wisconsin Dells with a missing girl who overdosed on heroin. When he found her dead, he took her body and dumped it in the woods.
