Unbeknownst to them, the Shriver home was being used to distribute fentanyl, cops say.

A Cape Cod home belonging to relatives of the Kennedy dynasty was being used as a base in a drug distribution operation, cops say.

Barnstable Narcotics Detectives and the Cape DEA Office in Massachusetts have been investigating two suspects they say are involved in moving the highly potent opiate fentanyl on a large scale.

According to information made public Thursday, the alleged drug pushers were using a Hyannisport property that records show is owned by a company managed by Robert Sargent "Bobby" Shriver III, son Sargent and Eunice Kennedy Shriver.

Mrs. Kennedy Shriver founded the program that became the Special Olympics. Her daughter, Maria Shriver, is a former TV journalist who married actor and politician Arnold Schwarzenegger in 1986.

Barnstable police say they charged Troy Monteiro and Trevor Rose with multiple drug crimes Wednesday after authorities say they seized more than 200 grams of fentanyl worth about $40,000.

The property caretaker was responsible for allowing the suspects to use the Shriver residence, according to police.

That caretaker has not been identified.
