Investigators have identified two additional possible victims in the case of a Columbus chess teacher accused of molesting one of his students at a Polaris-area preschool.

A Delaware County grand jury April 29 indicted F. Leon Wilson, 61, on two counts of gross sexual imposition, both third-degree felonies, according to court records. The indictment stems from Wilson's alleged sexual contact with a juvenile student between March 31 and April 7 at Prep Academy Schools' Polaris campus, 3812 E. Powell Road in Orange Township.

Wilson was discharged from the Delaware County jail on Friday, May 1, after posting $250,000 bond, according to court records. His trial has been set for July 19.

The Delaware County Sheriff's Office arrested Wilson on April 23 at Port Columbus International Airport as he returned to the city after a trip. The arrest followed a parent's report that Wilson has "inappropriately touched" his daughter.

Sheriff's office spokeswoman Tracy Whited said police in Bexley and Columbus have identified two other possible victims since Wilson's arrest. Both girls are former chess students.

Wilson has not been indicted on charges related to either possible victim.

Whited said the sheriff's and prosecutor's offices will continue to lead the investigation into the case, even though some incidents allegedly occurred in Franklin County.

Wilson, the founder of the Columbus-based Chess Learning Center and KnightMare Chess Club, also taught chess in Bexley and other central Ohio communities.

Wilson initially faced a charge of rape, a first-degree felony, in Delaware Municipal Court, but that charge was dismissed pursuant to the grand jury's indictment.

Sheriff's officials have asked parents of possible victims to call detective Jason Campbell at 740-833-2837 or email him at jcampbell@co. delaware.oh.us. The sheriff's office has trained interviewers available to assist parents of children who may have been victims.

Officials said parents should talk to their children about personal and body safety, but refrain from interviewing their children about their interactions with Wilson to avoid disclosure of false information.
