Sean B. Regan, 63, was reported missing from Washington, D.C., after he left his group home on the morning of February 20, 2021, and failed to return by his 10:00 p.m. curfew. He was last seen in the 4300 block of Jay Street Northeast. The Metropolitan Police Department describes him as a white male, 5 feet 11 inches (NamUs and Charley Project give 5 feet 10 inches to 6 feet), about 140 to 155 pounds, with gray hair and brown eyes, and wearing black pants with white shorts over them, a black coat, and black shoes. Shoe size is listed as 11.

NamUs lists the case as MP80778 with last contact on February 20, 2021, and the case remains published rather than resolved, while the Charley Project classifies him as endangered missing and notes he is a dependent adult. The investigating agency is the DC Metropolitan Police Department Missing Persons Unit, agency case number 21-022723; Detective Matthew Batko is listed as the contact and MPD asked the public for assistance. There are few other details: he was expected home, did not arrive, and did not make contact afterward.

Did anyone in the Jay Street Northeast area or nearby see Sean on or after February 20, 2021, or have information about his movements that day?
