Even without a body in the case, grand jury members Friday decided there was enough evidence to indict 16-year-old Parrish Bennette, Jr. with the murder of Vaughn, his 14-year-old girlfriend.

Family and friends were hoping to encourage others to shed light on this case. They remembered Vaughn at an emotional vigil Saturday night near Madison High School.
