CHISHOLM — An initial investigation Tuesday, Dec. 3, into the discovery of bones in a Chisholm basement shows the bones are likely not human.

Chisholm Police requested assistance for the investigation from the Minnesota Bureau of Criminal Apprehension. The bones will be submitted for further analysis to confirm the initial findings.

“The Chisholm Police Department takes every report and potential lead seriously,” Chief James Vukad wrote in a social media post Tuesday. “Any detail — no matter how small — has the potential to help resolve open investigations.”

Vukad said the unsolved disappearance of LeeAnna Warner from the city in 2003 remains a top priority for his department.

Warner was 5 years old when she was last seen walking home from a friend’s house in Chisholm. Despite a massive search effort after her initial disappearance, no clear evidence was found. Her case has garnered national attention over the last 22 years.
