Topeka ? Prosecutors have told defense attorneys that a Shawnee County sheriff’s detective may have falsified information used in a charging affidavit, The Topeka Capital-Journal reported Wednesday.

Citing a notice from the county district attorney’s office, the newspaper reported that Erin Thompson stated she had spoken to people even though she hadn’t actually talked to them, and that the information was used in a charging affidavit.

It wasn’t immediately clear in which case the alleged misconduct occurred. The detective has not been charged.

The Associated Press sent an email Wednesday morning seeking comment from the Fraternal Order of Police lodge that represents sheriff’s employees. People who answered the phones at several phone numbers affiliated with Erin Thompson in the county said they were not the detective. Other numbers rang unanswered.

The sheriff’s office website shows that Thompson started with the department in 2001, working as a deputy with the offender registration and victim services unit and later as a detective in the criminal investigations division.

Prosecutors are required to notify defense lawyers about witnesses, including law enforcement officers, whose credibility may be in question because of misconduct. Lee McGowan, a spokesman for the prosecutor’s office, said he couldn’t comment other than to say there is “an ongoing investigation.”

Sheriff Herman Jones said “an individual” has been placed on paid administrative leave, and that his office is investigating. Jones said a case had been open for “a few months” but declined further comment, saying it was a personnel issue.

Under Kansas law, “knowingly destroying, tampering with or concealing evidence of a crime” is a felony if the evidence involves a felony crime.

Kansas Bureau of Investigation special agent Mark Malick said the agency is investigating a matter at the Shawnee County Sheriff’s Office, but he wouldn’t confirm that it involved the detective in question.
