Six youths have escaped from the Riverbend Treatment Center in two separate incidents in the last two months, according to three Missouri Division of Youth Services employees with knowledge of the facility. The three staff members asked to remain anonymous for fear of retaliation from their employer, but all confirmed that two groups of three youths escaped on separate occasions, one month apart, with one of the escapees later being killed during a criminal incident near Kansas City. Riverbend Treatment Center, located at 5910 Mitchell Ave., houses youth, ages 14 to 21, for an average of nine to 12 months. Those at the center could be there for a number of reasons, from robbery to not going to school consistently.
