Susan Mayo, 60, was last seen on June 17, 2017, in Wilmer, Alabama; her bank account and cell phone went dormant soon after. The Mobile County Sheriff’s Office was not notified for about a week, and investigators concentrated on people close to her, especially her 32-year-old son Nathaniel Sebastian, who lived with her on Glenwood Way and was reported evasive during questioning.

On September 6, 2017, after detectives returned with a new search warrant, Sebastian confessed at the scene and led officers to Susan’s body buried about three feet under the front porch inside a 55-gallon drum. The medical examiner ruled the cause of death a gunshot wound to the head. Prosecutors say Sebastian shot his mother, later struck the corpse, placed it in the barrel and buried it. He was arrested on charges including murder, abuse of a corpse and promoting prison contraband after a homemade handcuff key was found in his mouth during booking. Susan’s 81-year-old mother, Doris Clark, was also arrested on obstruction of justice allegations.

Does anyone have information about Susan’s last known movements or who she was in contact with in mid-June 2017?
