Former Wisconsin Prison Employee Pleads Guilty to Conspiring to Commit Bribery

Brad D. Schimel, United States Attorney for the Eastern District of Wisconsin, announced that on January 15, 2026, Luz Naranjo (age: 46) of Beaver Dam, Wisconsin, pleaded guilty to conspiring to commit federal programs bribery, in violation of Title 18, United States Code, Sections 371 and 666(a)(1)(B).

According to court documents, Naranjo, a former correctional officer at Waupun Correctional Institution (WCI), received two bribe payments of $3,000 for smuggling contraband—including tobacco, cellular phones, and controlled substances—into WCI for an inmate.

The Federal Bureau of Investigation investigated the case.

Assistant United States Attorneys Zachary J. Corey and Kevin C. Knight for the Eastern District of Wisconsin are prosecuting the case. Trial Attorney Aaron L. Jennen, of the Criminal Division’s Public Integrity Section, substantially contributed to the investigation.
