LOS ANGELES, Calif.–A man who worked at a juvenile hall in Downey was sentenced today to four years in state prison for attacking a teenage detainee.

D’Wayne Jordan, 58, was convicted Oct. 31 of one count each of assault by a public officer, assault by means likely to produce great bodily injury, corporal injury to a child and willful injury to a child likely to cause great bodily injury.

Defense attorney William McKinney asked the judge to grant probation, saying the defendant had spent most of his life in military service or law enforcement.

But Judge John Fisher denied his request, handing down a four-year sentence on the principal count of willful injury to a child, with jail time served or to run concurrent for all the other counts.

Jordan was indicted in connection with a Feb. 20, 2009, attack on a 13-year-old boy at Los Padrinos Juvenile Hall, where the defendant was working as an acting senior detention services officer.

The teenager was kicked, kneed, struck in the head and had his head slammed against the floor after banging on his door to go to the bathroom, according to Deputy District Attorney Natalie Adomian.

The boy–who was 5 feet 5 inches tall and weighed 130 pounds at the time–lost half of a front tooth and suffered a cut lip and a bump on the side of his head, the prosecutor said.

The judge also ordered Jordan to pay $360 in restitution to the boy’s father for the cost of repairing his son’s tooth.

McKinney immediately filed a motion for appeal of the judge’s sentence.

Jordan was discharged by the probation department, but appealed his dismissal, according to the District Attorney’s Office.
