Sebastian Henderson Kelley, 30, vanished from the Portland and Westbrook area of Maine in mid-June 2017 after a disturbing sequence of events. He reportedly suffered a serious head injury in an assault and was treated at Maine Medical Center before leaving the hospital on his own.

Family members say the silence that followed was out of character. He reportedly contacted his sister at an apartment on Gilman Street in Portland, with his final known contact placed around June 16 or June 17, 2017. Search efforts focused on the Presumpscot River, where Maine State Police divers and K-9 teams searched more than once, but those searches did not locate him. Authorities describe him as transient or unhoused at the time, and the Maine State Police continue to list the case among active missing-person investigations.

Anyone who knew Sebastian, saw him in mid-June 2017 in the Portland or Westbrook area, or has information about his whereabouts is asked to contact the Maine State Police, Major Crimes Unit-South.
