BRADENTON, Fla. (WFLA) — Manatee deputies are searching for a man after they said he went missing in a river at Marshall’s Landing in Bradenton Friday morning.

Deputies are calling the incident a possible drowning. The MCSO dive and drone teams spent hours Friday searching the area for the man.

Manatee County Sheriff’s Office public information officer Randy Warren said they were called to Braden River around 8:15 a.m. about a report from residents that there was a man trespassing on the west side of the river.

Deputies said they weren’t able to find the man but they were called back later after residents saw the man walking through the mangroves. When they returned deputies saw the man standing in middle of the river in about waist-high water.

According to MCSO, the man did not seem to be in distress at first and identified himself to deputies. He was known to law enforcement from his previous criminal history. His name is not being released as deputies have not been able to make a positive identification.

Deputies said they encouraged the man to come to shore. He told deputies he did not want to go to jail while he stayed in the water.

As they were getting ready to go into the water to assist, the man “said something about the current” and yelled for help before going underwater.

Deputies have yet to find the man and the sheriff’s office said there was an alligator spotted in the area Friday.
