A former college student charged with murder had his bond cut by more than half as he awaits trial early next year.The defendant, Tyler Allen Jones, 20, saw his bond dropped from $750,000 to $300,000 by Circuit Court Judge Bart Stanley. He is charged along with five other Coffee County youths for the murder in January of Mt. Leo resident Oswaldo Luna, 43, during a drug robbery gone bad.Three of the six have seen their bond reduced, but all six still remain held at Warren County Jail.Prosecutors say Sam Brinkley, then 17, was the triggerman who shot Luna while he slept in his small trailer.
