The Door County Sheriff's Office is looking for a man who hasn't been seen since Monday.
In a Facebook post, the sheriff's department says 63-year-old Dr. Jeffrey Whiteside, a physician from Grand Chute, was with his family at their boat slip in Ephraim when he walked away.
His family reported him missing Wednesday morning. The family and his office haven't heard from him.
Whiteside is believed to still be on foot in northern Door County. The sheriff's office and Ephraim Fire Department volunteers have focused their search in the Ephraim area.
Anyone with information on his whereabouts is asked to call local law enforcement.
