TOPEKA, Kan. (AP) — Prosecutors say a Shawnee County sheriff’s detective may have falsified information in charging affidavits.

The Topeka Capital-Journal reports that the Shawnee County district attorney’s office sent a notice to defense attorneys. The notice says the detective stated she had spoken with people with whom she hadn’t actually talked and that the information was used in a charging affidavit. It wasn’t immediately clear which case was tied to the allegation of misconduct.

Prosecutors are required to notify defense lawyers about witnesses, including law enforcement officers, whose credibility may be in question because of misconduct.

Sheriff Herman Jones said only that “an individual” has been placed on paid administrative leave, and his office is investigating. A Kansas Bureau of Investigation spokesman says the agency is looking into a matter in Jones’ office.
