A former Hudson Valley cop has allegedly been told to "shut up" and there would "a price to pay" if he talks about Jeffery Epstein's death.

Nicholas Tartaglione is a former cop in Pawling, Mount Vernon, Yonkers and Briarcliff Manor who's accused of killing four men in 2016. The dead bodies believed to be of four Hudson Valley men, who went missing in April 2016, were found on property owned by Tartaglione in Otisville, officials say.

The retired cop shared a cell with convicted sex offender Jeffrey Epstein when he reportedly first tried to kill himself on July 23 at the Metropolitan Correctional Center.

Tartaglione was separated from Epstein before Epstein's suicide this month.

Following the 66-year-old's death, Tartaglione claims guards at the prison have told him "shut up,” “stop talking” and “stop complaining,” amid questions about how Epstein was able to kill himself in federal custody, Tartaglione's attorney said.

“The clear message Mr. Tartaglione has received is that if he conveys information about the facility or about [Epstein’s] recent suicide, there will be a price to pay,” Tartaglione attorney Bruce Barket wrote in a letter to a White Plains federal judge, obtained by the New York Post.  “Whether or not the investigators into the suicide chose to interview Mr. Tartaglione about the attempted suicide to which he was witness or about how the facility is run and the conditions under which the inmates are forced to live, the correction officers know he has information potentially very damaging to the very people now charged with guarding him or their coworkers.”

Tartaglione's attorney believes those reasons along with "deplorable” conditions — including “a serious rodent and insect infestation” are why his client should be moved to another prison. Tartaglione is due in court on Wednesday.
