UPDATE (12 p.m. Tuesday)-- The Stone County Sheriff's Office is releasing autopsy results for a West Michigan couple killed in southwest Missouri.
The medical examiner says 70-year-old Paul and his wife, 69-year-old Margaret Brooks of Baldwin, Mich. were likely stabbed to death. Blunt force trauma was also a factor in their deaths.
A 15-year-old suspect and a 16-year-old suspect remain in the custody of juvenile authorities, who plan to try the runaways as adults in the case. The Springfield News-Leader reports the teen suspects face juvenile charges of first-degree murder, armed criminal action and burglary.
The Brooks' bodies were found Thursday night at a home south of Table Rock Lake, where they were seasonal residents.
A man saw two suspicious young men near the home and held them at gunpoint until authorities arrived. The teens had recently run away from Lives Under Construction Ranch, a nearby facility for at-risk youth.
