A former Ohio State Highway Patrol lieutenant facing charges of tampering with records and theft in Delaware County has pleaded not guilty to menacing, abduction and other charges in a separate criminal case in Washington County, Ohio.

William P. Elschlager, 47, of Marietta, entered a not-guilty plea in Washington County Common Pleas Court on Monday to six charges, including abduction, criminal trespassing, menacing by stalking and receiving stolen property. The Associated Press reports the charges stem from an affair he had with one of his troopers’ wife while he was post commander in Marietta.

A trial was set for Aug. 3. The Associated Press reports he is under house arrest after posting $25,000 bail.

Elschlager was also indicted on May 6 by a Delaware County grand jury on a charge of tampering with records and six counts of theft, all third-degree felonies. Prosecutors said charges were filed after two guns were found in his home.

“The guns had been in evidence during the time Mr. Elschlager was a patrolman at the Delaware County post of the Ohio State Highway Patrol,” Delaware County Prosecutor Carol O’Brien said after the indictment. “One gun was supposed to have been destroyed, while the other had been catalogued as having been returned to the owner.”

Prosecutors said Elschlager later left his position at the Delaware post and became post commander at the Marietta post.

An arraignment for the charges has been set for July 15 at 9:15 a.m. in Delaware County Common Pleas Court. A summons to appear in court has been issued to Elschlager.

Delaware County Common Pleas Judge Everett Krueger will preside over the case.

According to the Ohio Revised Code, sentences for third-degree felonies range from a fine to between one to five years in prison.

Officials from the Ohio State Highway Patrol said that Elschlager was fired on Feb. 1 for “conduct unbecoming of an officer” and other offenses after he was charged with the incident in Marietta Municipal Court.

Officials report Elschlager had been with the Ohio State Highway Patrol since 1997.
