Once at the prison, she allegedly purchased a sealed chicken sandwich, unsealed it, and put it in the microwave to heat up. She then gave the sandwich to a corrections officer to search, and he found a plastic handcuff key in it, according to the arrest record.
The affidavit says Denlinger made it through three prison fences and four gates before she was caught with the contraband. She also went through a metal detector, and her personal items went through an x-ray scanner, according to the state Department of Corrections.
Denlinger did speak with investigators, but her comments have been redacted from the arrest report.
