LAKE COUNTY, MI — The body of former Grand Valley State quarterback Cullen Finnerty has been found, authorities said late Tuesday evening.

Finnerty, 30, was last heard from Sunday evening and was fishing near the Bray Creek area of the Baldwin River at the time of his disappearance.

His body was located in the Bray Creek Campground by the Osceola County Search and Rescue Team, about a half a mile from where his boat was found earlier in the search, Lake County sheriff Robert Hilts said.

The Grand Valley State graduate led the Lakers to national championships in 2003, 2005 and 2006. He has a wife and two children.

"It's such a tragic loss," said Grand Valley State football coach Matt Mitchell. "After seeing the members of the family out there searching today, it's just so very tragic."

A bus carrying 38 members of the current football team and coaches spent the day assisting authorities in the search for Finnerty.

"Word came across on the radio and the news began to filter through," Mitchell said of receiving word that a body had been found.

The bus returned to campus shortly after 9:30 p.m.

"It was a very solemn," he said.

Professional search teams, the Michigan State Police and other volunteers joined the sheriff's department in a search lasting more than 48 hours.

Family members told authorities Finnerty may have been experiencing an episode of stress or paranoia at the time of his disappearance.

Hilts said nothing at the scene indicated any potential causes of death, but no foul play is suspected.

Finnerty's body will be sent to Spectrum Health Butterworth Hospital in Grand Rapids for an autopsy.

Hilts said the department would release more information Wednesday morning.
