Summary based on the NamUs case record (MP149602) and 12 other sources
Luke M. Benoit, 31, was reported missing on June 28, 2022, from Portsmouth, Rhode Island. Police and local coverage state he was last seen that afternoon in the Boyd’s Lane area and was considered endangered after making concerning statements to family. The case remains under investigation by the Portsmouth Police Department and is listed in the National Missing and Unidentified Persons System as MP149602.

At the time he disappeared, Benoit was described as about 5 feet 6 inches tall with brown hair, brown eyes, a dark brown beard, and forearm tattoos reading “Carter” and “Emilia.” He was last reported wearing a gray Adidas T-shirt and a gray and black baseball cap in the Boyd’s Lane area. These details were shared in police alerts and local reporting soon after he went missing.

Publicly available timelines indicate Benoit was seen earlier that day at the Neon Marketplace in Portsmouth at approximately 1:27 p.m., where he purchased two packs of cigarettes, two bottles of water, and a bottle of ginger ale. Family accounts reported by local outlets say he made troubling statements by phone around the time he vanished, and that his phone later died or was turned off.

Search efforts began in and around Portsmouth soon after the disappearance. Community-organized searches gathered at the Park and Ride lot on Boyd’s Lane, about half a mile from where he was last seen. Over the weeks that followed, relatives, friends, and volunteers continued to comb wooded areas, while official records note extensive searching across land, water, and air in the area where he was last observed.

In the months after June 2022, the community continued to rally around Benoit’s family. Local news highlighted sustained searches and appeals for information that autumn, and by December 2023, coverage focused on efforts to support his loved ones during the holidays. Separate reporting noted a tip that he might have been seen in Fall River, Massachusetts, in October 2022, but no confirmed sightings have been announced publicly.
