MONCKS CORNER — A registered sex offender will spend the rest of his life in prison after a jury found him guilty of sexually abusing three children.

A jury took 40 minutes Wednesday to find Ronald Lee McCauley of Summerville guilty of three counts of criminal sexual conduct with a minor in the first degree, three counts of unlawful conduct toward a minor and two counts of lewd act upon a child, according to a statement released by the Ninth Circuit Solicitor’s Office.

Circuit Judge Kristi Harrington sentenced McCauley to three terms of life without the possibility of parole.

McCauley was released from prison and placed on the sex offender registry in 2006 after serving time for similar charges.

According to testimony during the two-day trial, McCauley be-friended the children’s mom, who allowed him to babysit her children even though she knew he was a registered sex offender.

Prosecutors said he physically and sexually assaulted the children repeatedly in 2007 and 2008 at both his home and at their home.

One of the children told the mother about the abuse but she allowed him back into the home anyway, according to the solicitor’s office. The children testified against McCauley.

The mother faces three counts of unlawful conduct toward a child. Her case is pending.

Assistant Ninth Circuit Solicitor Anne Williams said she is relieved McCauley will spend the rest of his life in prison.
