The NYPD is trying to figure out how a man in need of medical attention wound up floating face down in the Bronx River.

The man was identified by family members as 43-year-old William Daughtrey of Williamsbridge, according to News 12. 

Daughtrey has been missing since February. His mother, Barbara Felder, said he struggled with mental illness, according to News 12.

The cops initially said they received a call at around 2:30 p.m. on April 13 for a man in need of medical attention at Botanical Square, a small street less than a mile from the river. They later discovered the body in the waterway that cuts through the Bronx Zoo and New York Botanical Garden.

“Sometimes things don’t surprise you, living in the Bronx,” said Timothy, 47, an employee of the garden. “This was surprising.”

Investigators found no clear signs of trauma to the body, which was removed by the Police Department’s Emergency Service Unit and declared dead at the scene.

This was not the first dead body found in local parks this year. The remains of an unidentified man were found in French Charley’s Park in early January, and another dead body was found in Van Cortlandt Park days later.

Still, for locals in Bedford Park, next to the garden, news of the dead man came as a shock.

“That is a little scary,” said Sharon, program director at TCK Martial Arts on Webster Ave.  “I’ve always felt like this is a bubble of safety. Even though it’s the Bronx, I’ve never felt unsafe here.”
