Authorities are investigating after a man’s body was found in a “remote” cabin near Sandstone.

The body of 36-year-old Christopher A. Etchison was discovered Tuesday, four days after he was reported missing to the Barron (Wis.) Police Department. His cause of death remained under investigation Wednesday, according to law enforcement officials investigating the case in both Wisconsin and Minnesota.

Two suspects were arrested in connection with the case Monday, a day before Etchison’s body was found, though they have yet to face any formal charges in either state.

Barron police were first alerted to Etchison’s disappearance when a family member called Friday morning. Later that night, his parents came to the police department to fill out a missing person report, and his name was added into a National Crime Information Center database.

On Monday, “several leads were developed” that led to the execution of a search warrant at Etchison’s residence, police said. Three potential suspects were questioned and arrested.

The Pine County Sheriff’s Office reported that it was notified early Tuesday that Etchison could possibly be at a cabin east of Sandstone. Investigators were able to identify a location on McDermott Creek Road, where he was discovered dead at about 11:15 a.m.

There was “no obvious cause of death,” the sheriff’s office said in a news release. Etchison’s body was taken to the Midwest Medical Examiner’s Office for an autopsy.

Two suspects remained jailed Wednesday. The men, 18 and 20 years old, were facing preliminary charges of identity theft and obstruction. An 18-year-old woman, who was booked on an obstruction charge, was released from custody.

The News Tribune generally does not identify suspects until they have been formally charged.

An investigation is being conducted by the Barron Police Department, Pine County Sheriff’s Office and Minnesota Bureau of Criminal Apprehension.
