A jury of 10 women and two men heard opening arguments from the prosecution Monday in a former law enforcement officer’s trial on sexual battery and incest charges.

London Williams, 40, 4425 Nailor Road, who has held various ranks with the Vicksburg Police Department and the Warren County Sheriff’s Department since 2003, was indicted by a grand jury on one count each July 28 following an investigation of a complaint from an adult victim by the Mississippi Bureau of Investigation, the detective arm of the state police. If convicted, Williams could face up to 30 years on the sexual battery charge and 10 years on the incest charge.

Circuit Judge M. James Chaney is hearing the case, which was expected to continue this morning with more prosecution witnesses. Testimony on Monday came from the victim and an MBI investigator.

District Attorney Ricky Smith is prosecuting the case, which drew about 200 Warren County residents for jury duty. Williams is defended by Jackson attorneys Michael Marks and Andy Sumrall.

The jury is made up of seven white women, three black women, one white man and one black man.

The complaint against Williams was made May 6 to VPD, where Williams was a patrolman in 2003-04 and for about 10 months in 2007. Sheriff’s department officials received the case upon later information that the alleged incident took place outside city limits. The sheriff’s department, in turn, conducted an internal inquiry and contacted MBI.

After an unsuccessful run for sheriff in Issaquena County, Williams was an investigator during his second stint with the Warren County Sheriff’s Department, from January 2008 until June, when his employment ended. At the time he was indicted, officials did not say whether he quit or was fired. He had been placed on medical leave from the department in April after he was injured in a wreck.
