SAN ANTONIO -

On Thursday, the Fourth Court of Appeals affirmed the conviction of a Bexar County juvenile detention guard who was found guilty of a host of child sex abuse charges.

Miles McFadden, 32, was convicted in December on 10 counts, including continuous sexual abuse of a child, aggravated sexual assault of a child, sexual assault of a child, and indecency with a child.

According to a statement issued by the Bexar County District Attorney’s Office, in December of 2005, McFadden began to foster two young boys, ages 11 and 3, whom he would adopt a year later.

According to testimony during McFadden's trial, McFadden almost immediately began to sexually assault the older boy.

According to testimony, he sexually assaulted the victim twice a week from the time the boy was 10 until he was 14.

The abuse continued weekly until the boy outcried to a neighbor in July of 2010.

According to the DA's statement, subsequent forensic testing showed the presence of Chlamydia Trachomatis, a sexually transmitted disease, in both McFadden and the boy.

McFadden was employed as a juvenile detention officer at the Bexar County Juvenile Detention Center.

On appeal, McFadden claimed that the evidence was insufficient to support his conviction and, according to the statement, the Fourth Court of Appeals "rejected his claim and concluded that the evidence, which included the victim's testimony about the four years of sexual abuse, was sufficient to support the conviction."

McFadden must serve the five life sentences concurrently.
