LINCOLN, R.I. (AP) — The son of a reputed Rhode Island mobster walked into a state police barracks unharmed four days after being reported missing.

State police told WPRI-TV that 45-year-old Robert DeLuca Jr. of North Providence went to the Lincoln barracks sometime after 8 p.m. Wednesday. North Providence police issued a missing persons report for him after his mother told authorities she hadn't heard from him since Sunday.

DeLuca is the son of Robert DeLuca, who has been named by the FBI as a reputed captain in the Providence-based Patriarca crime family.

Police say they initially didn't suspect foul play in the younger DeLuca's disappearance, but the case caught the attention of federal agents because of who his father is.

Authorities say it's not clear where Robert DeLuca Jr. had been.
