The Kingsport Times News reported that the 29-year-old worker at Sullivan East High School denied taking money from a co-worker's purse. The woman then told officers she'd strip to prove it.
Police told the woman disrobing wasn't necessary, but she took off her shoes and socks during the interview last week.
Police say the woman then removed the rest of her clothes and told officers "See, I don't have it."
Police then checked a shoe she had removed, finding $27 stuffed beneath the insole.
The woman told officers the shoes belonged to her husband.
The woman was charged with theft.
