Investigators have recovered the body of a missing 40-year-old Webster man.

Shawn Ross vanished Thursday during a day out on the Irondequoit Bay with a friend and family member. They were on a pontoon boat when Ross jumped in the water around 5:15 p.m. He was wading in waist-deep water when he went under. The two people with him searched, but when they couldn't find him, called 911 about half an hour later.

Chief Deputy Michael Fowler says the conditions of the weather and the water made all the difference for search crews. Side-scan sonar also played a major role in the discovery of the body in the area of Sand Point. It was able to pinpoint the location of Ross' body so divers could go right to that spot.

Fowler says the body was located about 45 feet offshore, just north of the Bay Bridge.

The Monroe County Sheriff's Office, State Police, and Coast Guard searched for Ross into the night Thursday. The Sheriff's Office halted the search around 12:30 a.m. as bad weather and the murky water made it a challenge to find anything.

Chief Deputy Fowler says a change in the landscape may be to blame for Ross' death. He was a swimmer but fell into an area where there is a sharp 60 feet drop.

"Our best guess at this point is... indications are that he lost his footing and got caught up in that sudden change in depth and was able to recover himself," Chief Deputy Fowler says.

The chief deputy described the conditions of the water, saying imagine not being able to see further than your hand.

Family members of Ross were brought to the location earlier Friday morning.

EARLIER:

Crews are now calling the search for a missing Webster man last seen in the Irondequoit Bay a recovery effort.

Forty-year-old Shawn Ross was last seen around 5:15 p.m. Thursday. He'd been out on a pontoon boat with a friend and family member. He hopped out of the boat and into the water on a sandbar. Deputies say the group was playing water sports and then he disappeared. The group was about 25-50 feet from the shore.

Crews believe if Ross was a good swimmer he may have made it to land. Crews found the pontoon boat and secured it.

When asked if they had been drinking, investigators are trying to figure that out. Officers say there's no reason to believe he was upset and wanted to get away from the people he was with.

Chief Deputy Michael Fowler says it is now a recovery operation. He also adds they have no confirmation Ross is still in the Irondequoit Bay.

Crews are using sonar technology to identify possible search locations then divers will then enter the water.
