Seventeen-year-old Mariotis Harris was found dead in a secluded patch of woods known as the Gladeside Urban Wild near 90 Lorna Road in Mattapan, Boston, in the early hours of Sunday, June 3, 2007. Police responded to a call at about 12:30 a.m. and discovered Harris in that wooded area.

The Office of the Chief Medical Examiner ruled the death a homicide, caused by a gunshot wound. Reports said he had been shot in the back of the head, which suggested he had been led into the woods before he was killed. The Boston Police Homicide Unit opened an investigation, but no arrests have been publicly announced and, as of late 2007, no suspects or persons of interest had been identified.

The case remains unsolved. If anyone knew Mariotis, had information about his movements on June 2–3, 2007, or saw anything near the Gladeside Urban Wild that night, please come forward.
