A Blue Earth County man who went missing on Thursday — while apparently trying to clear a drainage ditch — is believed to have drowned.
That afternoon, a vehicle belonging to 92-year-old Amboy resident Marvin Borkenhagen was spotted unoccupied near the ditch, which is located at County Road 32 and County Road 144 in Pleasant Mound Township, according to a news release from the local sheriff.
Authorities soon responded to the scene and found a tool belonging to Borkenhagen in the water near a culvert that feeds into the ditch, the release says.
The sheriff's office also reported that Borkenhagen has been known to sometimes free ice and debris from the culvert.
Water in the ditch is believed to be around eight feet deep, and flowing at a "steady rate."
A subsequent search for Borkenhagen included the efforts of multiple departments, the DNR, and a Minnesota State Patrol helicopter. It was called off overnight but resumed Friday.
And though the search continues, the case is considered a probable drowning.
Borkenhagen's disappearance comes as Blue Earth County braces for serious flooding, with the county board having declared a state of emergency to offset any damage to local infrastructure, the Mankato Free Press reports.
