Fascinating twist in the story of the dead body caught by fishermen in the waters off Massachusetts … turns out the corpse was meant to be buried at sea and no foul play is suspected, according to authorities.

The Suffolk County Chief Medical Examiner in Boston just announced the body is a woman in her 60s with cancerous tumors all over it. The M.E. says the unidentified body was embalmed and apparently intentionally deposited into its watery grave.

Prosecutors say the case is now closed, adding the dead woman will likely stay nameless forever.

And today, TMZ snagged more footage showing authorities removing the body from the fishing vessel at the Boston Seaport. Officials from the Medical Examiner were seen loading the corpse onto a gurney and into an SUV.

Ray “Roy” Edward Chasez, the father of JC Chasez, has died … TMZ has learned.

Sources tell TMZ … Roy died last month in Florida after a battle with cancer. This was his fifth bout with the disease.

We’re told a celebration of life was held on Saturday in the Orlando area and multiple members of *NSYNC attended.

Roy worked as an IT manager, and also as a contractor with the government … with offices at the White House and U.S. Postal Service headquarters in Washington, D.C. We’re told he worked with numerous charities over the years … and his family was his life.

He’s survived by his wife of 51 years, Karen, and his children — JC, Heather and Tyler.

Roy was 73.

The Menendez brothers‘ relatives, who are also victims in their murder case, are ripping L.A. County D.A. Nathan Hochman … claiming he’s being hostile, dismissive and patronizing.

Erik and Lyle‘s cousin Tamara Goodell laid out the family’s issues with Hochman in a formal complaint to the United States Attorney’s Office Civil Division … blasting L.A.’s new top prosecutor for allegedly violating their rights as victims.

In the complaint, obtained by TMZ, Goodell claims Hochman is re-traumatizing the family now that he’s sinking his teeth into their case.

The family claims Hochman created an intimidating and bullying atmosphere with a hostile, dismissive and patronizing tone … leaving them feeling distressed and humiliated.

What’s more, Goodell claims Hochman made the meeting about himself rather than the victims … turning the sit-down into a lecture about how he was being treated, rather than taking the opportunity to hear out the victims and respect their voices.

She says the “lack of compassion was palpable” during the meeting and the family left feeling not only ignored, but also intimidated and re-victimized.

Erik and Lyle’s cousin claims Hochman is violating the family’s rights under Marsy’s Law … which protects the rights of crime victims.

Specifically, the family says Hochman’s dismissive, aggressive, and shaming behavior is a direct violation of their rights to be treated with fairness and respect and be free from intimidation, harassment, and abuse.

The complaint comes on the heels of Hochman’s latest press conference, where he said the Menendez brothers should not be resentenced because they haven’t shown remorse for the murders, or copped to all the lies they told to cover their tracks.
