JENISON (WKZO) -- An extensive search for a missing Georgetown Township woman Wednesday came up empty.

60-year-old Gail Masselink of Jenison has apparently been missing since Sunday.  Those involved in the search tracked her cell phone to her car, found abandoned at the end of 12th Avenue where it dead-ends near the Grand River.  The vehicle was unlocked and the keys were left in it.  They used side-scan radar to search the river and volunteers from Southwest Michigan Search laid out a grid pattern and searched for clues.

Masselink was last seen wearing a long puffy Northface coat and hiking boots.
