Peter Robert Carocci, 21, vanished during a fishing trip off Narragansett, Rhode Island on August 15, 1987. He and a friend, Michael J. Sweet, planned a four-hour outing; neither returned. A 19-foot outboard motorboat they were using was later found swamped and adrift about 15 miles southeast of Block Island. A U.S. Coast Guard search of the area turned up no sign of either man. It is not known whether they were wearing life jackets.

The Narragansett Police Department opened an investigation under case number 87-1959 for Carocci. The disappearance has been entered into NamUs as MP40219. Beyond the swamped boat and the unsuccessful search, the circumstances that led to the men going missing remain unclear.

Anyone with information about where Peter Carocci or Michael J. Sweet might have been that day is asked to contact the Narragansett Police Department tip line at 401-789-8967.
