Four teenagers who escaped from a Saline County juvenile lockup have pleaded guilty to theft of property and escape. The teens -- 17-year-olds Tony Brooks and Ozzie Brown of Pulaski County, Christopher Brickey of Hot Springs and 15-year-old Justin Ewell of Little Rock were sentenced to adult prison terms. But Ewell won`t go to jail until he`s 16. Authorities said the teens lured a guard into their cell at the Alexander Youth Services Center in Bryant. Officials say they locked him in the cell, stole another worker`s car keys and used it to ram through the center`s gate. Saline County Circuit Judge Gary Arnold sentenced Brooks and Brown to six years each in prison. Ewell and Brickey were each sentenced to six years, three suspended. Their trial was set to begin Wednesday.
