A 64-year-old man died while diving in the Straits of Mackinac on Saturday afternoon.
Dennis Javens, of Mankato Minnesota, was diving to see the sunken vessel, Cedarville, east of the Mackinac Bridge with friends on a private boat.
According to the Cheboygan County Sheriff's office, Javens ran out of air and was unable to return to the surface.
"He was with a partner and the buddy systems was used but at some point Mr. Javens became unresponsive and his partner was unable to get him to the surface," says Sheriff Clarmont.
Javens' diving partner came up from the water and a call for help was placed. A crew member from the Northern Michigan Dive Center, who was doing a separate dive on the Cedarville at the time, was able to bring Jarvens to the surface.
Jarvens was rushed to the shore where emergency personnel tried to revive him. Jarvens was pronounced dead at the scene.
"From the investigation it appears Mr. Javens was under the water for about 20 minutes," says Sheriff Clarmont.
"All the equipment was inspected and found to be in working order and the main tank was still full," says Clarmont, "It appears from the investigation that Mr. Javens started on his reserve tank and when it ran out of air, thinking it was his main tank, attempted to go to his reserve which was empty."
The sheriff's office says that an autopsy is scheduled for Monday morning at Spectrum Health Hospital in Grand Rapids.
