A former law enforcement officer has won appeal for resentencing, but it could cost him more time in prison.

London Williams, 42, 4425 Nailor Road, was sentenced in November 2010 by Circuit Judge M. James Chaney to seven years in prison followed by five years’ probation. The sentence was ruled illegal by the state Court of Appeals because it exceeds sentencing guidelines of a combined 10 years.

At his resentencing, which has not been scheduled, Williams could be sentenced to 10 years in prison followed by no probation, District Attorney Ricky Smith said.

Since his conviction, Williams has been held in Mississippi State Correctional Facility in Parchman. His tentative release date is Nov. 16, 2017.

Upon his release, Williams will not be required to register as a sex offender, Smith said.

“Incest is not specifically listed in the sex offender statutes,” Smith said.

Williams was convicted Nov. 2, 2010, of incest after he admitted in court to having sex with an adult relative. On the stand, he insisted the sex was consensual and was found not guilty of a second charge of sexual battery. At first, Williams denied any sexual contact with the relative, according to his appeal.

A jury of 10 women and two men took only 30 minutes to return a conviction.

The complaint against him was made May 6, 2010, by an adult victim to the Vicksburg Police Department, where Williams was a patrolman in 2003 and 2004 and for about 10 months in 2007.

At the time of his arrest in July 2010, Williams was an investigator with Warren County Sheriff’s Department.

Mississippi Bureau of Investigation investigated the case after it was determined that the crime happened outside the city limits and in the jurisdiction of the sheriff’s department.

Williams worked for the sheriff’s department twice, before and after an unsuccessful run for sheriff in Issaquena County. He left the department just before the arrest.

Williams had been placed on medical leave from the department in April 2010 after he was injured in a wreck.

Williams’ conviction rendered a number of criminal cases in which he was the lead investigator “unprosecutable,” according to court documents.
