Massachusetts State Police responded to the banks of the Neponset River off Granite Avenue in Milton Tuesday after “a partially submerged body was observed”.

The remains, which Norfolk District Attorney Michael Morrissey’s office said “appeared to have been in the water for a significant time”, were taken to the Chief Medical Examiner’s office to investigate cause and manner of death.

“While positive identification will need to be finalized by the medical examiner, the man had materials on his person with the name of a male in his 50s reported missing out of Suffolk County in December,” Morrissey’s office said in a statement.

The body was recovered shortly after 11 a.m., and the scene was clear by 11:37, authorities said.

This death remains under investigation.
