David Anderson was 36 when he was killed in the late hours of March 15, 2016, in a third-floor Gilman Street apartment in Portland, Maine. Surveillance showed a figure, mostly in black with a covered face, standing outside the apartment door and firing multiple rounds through it. One bullet killed Anderson; another man inside was wounded and survived. The shooting happened about a week before Anderson’s 37th birthday.

At the time, Anderson was homeless and struggling with drug addiction, often staying with friends including the Gilman Street tenant. His family described him as a loving brother who nevertheless was involved in selling heroin, a factor believed to have contributed to the circumstances leading to his death. Police initially identified a person of interest as a white male about six feet tall with a medium build.

In August 2020 a grand jury indicted Aristotle Stilley, who was arrested in October in Sacramento and extradited to Maine. Stilley said he was innocent; the prosecution relied largely on circumstantial evidence, including cell phone records, and the defense pointed to limited physical evidence. A jury ultimately found Stilley not guilty, and Portland police closed the investigation, leaving Anderson’s slaying officially unsolved.
