A DCR worker discovered a man's body in the Muddy River in the area of the Bowker overpass around 10 a.m. today, the Suffolk County District Attorney's office reports.
A tentative identification has been made based on a missing-person's report, the DA's office says, adding foul play does not appear to have been involved.
It's the same general location where bodies were found in June and March.
Authorities have also recovered three bodies from the Charles River this year, in May, June and August, although the August recovery was the result of a suicide that other people witnessed.
Some partial human remains were also recovered in June, but State Police said at the time that was related to a specific criminal investigation already underway, not a new body.
DA spokesman Jake Wark says none of the full-body recoveries have been tied to foul play and that there's no connection between any of them:
Investigators don't believe the deaths are connected in any way. As with many of these cases, the only common factor is the presence of water. A person who falls into the water for whatever reason - accident, impairment, or what have you - is, for obvious reasons, simply more likely to die as a result than a person who falls on land.
