Matthew Eric Silveira, 32, of Beverly, Massachusetts, was last seen by friends in Wellfleet on July 5, 2020, and reported missing later that month. His vehicle was found abandoned on July 12 along Black Pond Road near the Cape Cod National Seashore in Wellfleet. Inside the car were his cellphone and camping gear.

Timeline fragments place him moving through southeastern Massachusetts in the days after July 5. On July 6 he stopped at a gas station in Plymouth and was seen driving back toward Cape Cod. He crossed the Sagamore Bridge at about 3:30 AM on July 7, and his phone last pinged early that morning in Yarmouth. His phone pinged again on July 13, but searches by local authorities and the National Park Service turned up no trace of him. Family and friends reported prior concerning statements about his mental health; the isolated location of the vehicle has intensified worries about his welfare. Large-scale searches were suspended in August 2020 for lack of new leads.

If anyone saw Matthew in July 2020 or has information about his movements around Cape Cod, please share what is known.
