Frank Robert Mazzella Missing Person Case

Frank Robert Mazzella disappeared under mysterious circumstances on February 7, 1999, from Westerly, Rhode Island. More than two decades later, investigators continue to classify his disappearance as an Endangered Missing case, with no confirmed evidence explaining what happened.

Mazzella, 39 years old at the time, was last seen by relatives at approximately 9:00 a.m. inside his apartment on the 100 block of Oak Street. According to investigators, nothing initially appeared out of place. His vehicle remained parked outside, and his wallet, personal belongings, and other possessions were left behind inside the residence—an unusual circumstance suggesting he did not intend to leave voluntarily.

Concern grew later that day when Mazzella failed to pick up his son from school, something family members considered highly uncharacteristic. After attempts to reach him proved unsuccessful, authorities were notified and an investigation began.

Despite extensive inquiries, investigators have never publicly identified a suspect or announced evidence indicating whether Mazzella met with foul play, suffered a medical emergency, or voluntarily disappeared. No verified sightings have been reported since the morning he vanished.

The case has remained active through the years and is listed in the National Missing and Unidentified Persons System (NamUs) as MP99, allowing investigators nationwide to compare unidentified remains and missing person records. Law enforcement has encouraged anyone with information—even information that may seem insignificant—to come forward.
