Barnesville, MN (Learfield)  --  The Minnesota Department of Natural Resources says there's not enough evidence to file charges that a truck illegally herded deer on a property in Barnesville.

That  northwestern Minnesota land is owned by Dr. Walter Palmer, the dentist who got unwelcome attention for killing a lion in Zimbabwe.  

The D-N-R says witnesses weren't able to identify a suspect and investigators couldn't tie the trucks to Palmer or his property manager.  A spokesperson for the doctor called the complaint a false and baseless attack.  

Palmer was identified last summer as the killer of Cecil, a famous lion in Hwange National Park, drawing worldwide criticism.
