A father of four vanishes into thin air...

Luke Benoit was last seen walking in his hometown of Portsmouth, RI.

At 1:27 p.m., Luke is seen at the Neon Marketplace where he purchased two packs of cigarettes, two bottles of water, and a bottle of ginger ale.

Luke made his final call to his wife nine minutes later and made comments that his family says were "concerning" regarding his well-being and state of mind. His cell phone last pinged at around 2 a.m. on June 29 in the area of the Sakonnet River Bridge.

Luke was never seen or heard from ever again. His bank accounts also have had no movement since his disappearance. Searches have also turned up nothing.

"Luke, if you see this, please come home. We love and miss you," his aunt, Marsha Langello, said. "Your children need you, your family needs you."

Luke's family members are banding together in their community to support Luke's four young children and wife Stephanie, who are struggling to comprehend his absence. Local stores and restaurants have donated food and time to the family, who will never forget their community's kindness.

To this day, Luke's whereabouts are still unknown. Do you know where he is?
