The Office of the Chief Medical Examiner eventually determined Jeremiah’s death to be a homicide and listed the cause of death as “homicidal violence of undetermined etiology,” the release states.

Sierra was dating Jeremiah’s mother, Elsa Oliver, at the time of the boy’s disappearance, which was reported two months later after the boy’s older sister expressed her concerns to a teacher,CBS News reports.

In 2017, Sierra was sentenced to six-to-seven years in prison for assaulting Elsa Oliver and Jeremiah’s two surviving siblings, according to the district attorney.
