A Grand Rapids fireman hasn't been seen nor heard from in about day since his boat caught fire and sank at Barrett Boat Works.

Crews removed the sunken boat around 6:30 p.m. Sunday, May 8, from the Ottawa County marina hours after it sank early in the morning. Officials confirm the finding of a body, but they cannot yet identify it.

That will take some time, they say.

Firefighters responded to a call from a nearby condominium resident just after 5 a.m. on a report that a boat was up in flames, said Ottawa County Sheriff's Department Captain John Wolffis. Upon arrival, the 36-foot vessel was fully engulfed.

The boat eventually sank.

Its owner, identified as David Knisley, is a Grand Rapids firefighter, Wolffis said. Friends and family have yet to get in contact with him since he was last seen Saturday night.

Knisley was spotted in the marina at that time, but it is not certain whether he actually was on the boat, Wolffis said.

A friend told WZZM's Meredith TerHaar that Knisley's vehicle still is in the parking lot of the marina.

Crews used an underwater camera earlier in the day to search beneath the water. They had lifted the boat a few inches out of the water to tow it to the dock.

While one boat caught fire and sank, a nearby boat received extensive smoke damage.
