The trial of a teen accused in one of Marion County's most brutal murders has been delayed for at least six months.
Michael Bargo and four teens were charged in the death of 15-year-old Seath Jackson.
According to investigators, Jackson was beaten and dismembered during a planned attack.
A defense expert said Bargo suffered from mental illness as the result of head injuries when he was young.
Bargo will undergo tests to determine whether he's competent to stand trial.
