A Mason County car ferry worker spotted the body of a Ludington man missing since last December.
   That person discovered the body floating in water near the S.S. Spartan car ferry off the waters of Lake Michigan in Ludington, according to police.
   Officers say the Lake Michigan Car Ferry employee spotted the body of Gabriel Michael Smith just after 3 p.m. Thursday.
   Police say a medical examiner identified Smith's body -- crews then took it to a Grand Rapids hospital for an autopsy.
   Police say Smith was reported missing December 10th and was last seen walking on Foster Street near James Street in the early morning hours of December 8th.
