Andrew Nevenheim left his Rochester home at about 6 p.m. Thursday to walk his dog, as he does most evenings. But he never came home.

Nevenheim 46, was reported missing to the Rochester Police Department after his family could not find him Thursday evening.

He was last seen leaving his house around 6 p.m. to walk his dog, Capt. Casey Moilanen said. At 6:30 p.m., the family got a call from a neighbor that their dog had been found walking around off its leash and unattended.  

The family went to pick up their dog and then set out to find Nevenheim. His wife found his bike and dog leash unattended near Bear Creek close to the 400 block of Seventh Avenue Southeast.

The family called police at 8:42 p.m

There appeared to be no sign of struggle or violence at the scene, and it is feared that Nevenheim might have gone into the river. The water was moving quickly and might have swept him away, Moilanen said.

The fire department and the sheriff's office assisted in search efforts Thursday evening. The search had to stop because of thunderstorms, but resumed at 6:30 a.m. Friday. At 8:30 a.m., the search was paused to maintain equipment. The search resumed around noon, Moilanen said.

Nevenheim was wearing khaki shorts; a pink, tie-dyed shirt; red and white Adidas shoes, and red-lensed glasses. 

Anyone with information that might help locate Nevenheim, is asked to call the Rochester Police Department at 507-328-6800.
