Sebastian Henderson Kelley was 30 years old when he vanished in June 2017, a disappearance that began in the Portland and Westbrook area of Maine after a frightening sequence of events. Online missing-person records list him as a Black man, about 5 feet 11 inches tall and roughly 190 to 200 pounds, with black hair and brown eyes. He had several identifying features, including a tattoo reading “Willow Grace” on the left side of his neck; other public case summaries also describe tattoos on
his wrist and hand, piercings, and scars that could help distinguish him if someone recognized him. He was a son, a father, and someone loved deeply by family and friends, and those close to him described his sudden silence as completely out of character.
The circumstances around Sebastian’s disappearance were especially troubling because he had reportedly been assaulted shortly before he was last known to be seen. Public case information states that he had been treated at Maine Medical Center for injuries from an assault in Westbrook, and The Charley Project describes those injuries as including a serious head injury that left him in need of medical attention. After leaving the hospital on his own, Sebastian reportedly made contact with his sister at an apartment on Gilman Street in Portland. Public reports and case listings place his final known contact around June 16 or June 17, 2017, with NamUs and Maine State Police listing June 17, 2017, as the date associated with his disappearance from Westbrook.
In the days and weeks that followed, his loved ones became increasingly afraid that something had happened to him. News Center Maine reported in July 2017 that Sebastian’s sister had reported him missing and that friends and family had gone nearly a month without hearing from him. His fiancée, Cassie Doughty, told the outlet that it was not like him to go that long without contacting anyone, and she expressed hope that he was alive but frightened, injured, or unsure who he could trust. His high school sweetheart, Jessica Marr, who shared a young daughter with him, described the uncertainty as painful and said she felt something was wrong because the length of silence was not normal for Sebastian.
Search efforts soon focused on possible clues in and around Westbrook. WMTW reported that Maine State Police divers searched the Presumpscot River for evidence connected to Sebastian’s disappearance, including a second river search within five days near Ash Street. A nine-member dive team spent hours in the water, and state police and game warden K-9s were also used during search efforts along the river, but the search did not uncover answers. The fact that investigators returned to the river more than once shows how urgently they were trying to follow available leads, yet the searches left Sebastian’s family still facing the same devastating unknowns.
Years later, authorities continued to ask the public for help. Maine State Police list Sebastian’s case among missing-person cases and state that investigative efforts have not revealed his location. Public appeals describe him as having been transient or unhoused at the time and as having recently been assaulted, details that made his disappearance particularly concerning because he may have been vulnerable, hurt, disoriented, or unable to seek help. The agency has asked anyone with information to contact Maine State Police, Major Crimes Unit-South, and local reports in 2025 noted that police were still seeking new leads eight years after he was last seen.
Sebastian Kelley’s case is the story of a man who disappeared after suffering serious harm, leaving behind people who knew his silence was not normal and who have carried years of unanswered questions. He was last connected to the Portland and Westbrook area after an assault, medical treatment, and contact with his sister near Gilman Street, and despite searches, public appeals, and ongoing attention from law enforcement, his whereabouts have not been publicly resolved. The overview of the case is that Sebastian Henderson Kelley, age 30, was last known to be in the Westbrook and Portland, Maine area in June 2017 after a reported assault and hospital visit; he was described as 5 feet 11 inches tall, around 190 to 200 pounds, with black hair, brown eyes, and a “Willow Grace” neck tattoo; investigators searched for clues, including in the Presumpscot River, but no public source has reported that he has been located.Last Seen: Jun 17, 2017
