The sheriff department's former second-in-command pleaded guilty to misdemeanor theft charges on Friday in federal court.
Christopher Radtke, the Pima County Sheriff Department's former chief deputy, will be sentenced April 7 after pleading guilty to three counts of theft of government property before U.S. Magistrate Judge Eric Markovich.
Radtke's plea agreement with federal prosecutors resulted in each of the three counts being for theft of less than $1,000. He is facing up to one year of probation and an agreement to never work as a law enforcement officer or with Pima County again. The sentencing agreement has to be approved by the judge.
"We have reached a just outcome in this case," said U.S. Attorney John W. Huber of the District of Utah, which handled the case. "This investigation and prosecution has cleaned the Pima County Sheriff's Office of years of corruption and ensures it will not return."
Radtke was indicted in September on one felony charge of conspiracy to launder money and seven felony charges of theft concerning programs receiving federal funds, according to U.S District Court records.
Radtke resigned from his job two weeks after the indictment, which followed a months-long investigation by the FBI into high ranking department officials who allegedly misused public funds, according to Arizona Daily Star archives.
The investigation revealed that Radtke embezzled roughly $500,000 dollars of money seized from alleged criminals under the Racketeering Influenced and Corrupt Organizations Act, otherwise known as RICO.
RICO funds are intended to be used for crime fighting and prevention, but the indictment says that Radtke was misusing those funds, making purchases that didn't fall under those requirements.
Radtke admitted that for 18 years personnel at the sheriff's department would circumvent the strict restrictions on the use of so-called RICO funds. The officers collaborated to make it appear the department was donating the RICO money to the sheriff's auxiliary volunteers fund, although the funds were being used by the sheriff's department, according to a news release from the U.S. Attorney's Office.
Radtke admitted that he became part of the practice about six years ago, the release said.
The FBI investigation began after a November 2015 Star story about Radtke's niece, Nikki Thompson, running cafes inside sheriff's headquarters and the jail, without a county contract and rent-free.
Public records requests revealed that the sheriff's department spent more than $30,000 on renovations and equipment, the Star reported in November 2015.
Thompson was operating cafes inside headquarters and the Pima County Adult Detention Center without a county contract, and the department spent more than $30,000 in renovations and improvement to the locations.
The indictment listed a number of purchases, several of which were associated with cafe expenses.
The indictment listed a conspiracy charge and mentioned "other persons known and unknown to the grand jury," but no one else has been charged in connection with the investigation.
