Pima County Sheriff Calls for State Investigation into RICO Fund Usage

After revelations of a lengthy criminal conspiracy involving federal funds, Sheriff Mark Napier has requested a state investigation into the Pima County Sheriff’s Department. The request follows the September indictment of former Chief Deputy Christopher Radtke on felony charges related to conspiracy and theft.

Radtke accepted a plea deal in February, resulting in three misdemeanor convictions for theft of federal funds. He was sentenced to one year of probation, 100 hours of community service, and a $3,000 fine. Sheriff Napier’s decision to seek a state-level inquiry was driven by community and departmental concerns about the adequacy of Radtke’s sentencing.

In a statement, Napier noted, “After extensively conferring with the FBI, it appears there may be another avenue available that could be explored.” He emphasized the importance of addressing potential culpability beyond Radtke and asserted the necessity of a thorough investigation to solidify public trust.

The proposed state review will investigate the department’s use of funds under the Racketeering Influenced and Corrupt Organizations Act (RICO). This action aims to clarify allegations about the misallocation of resources that Radtke claimed had been occurring over nearly two decades.

Although Radtke was a central figure in the federal case, no other members of the department have thus far been charged. The FBI’s probe was initiated after concerns arose over uncontracted services at sheriff’s headquarters, specifically regarding a cafe run by Radtke’s niece. Initial claims regarding funding suggested misuse of RICO funds, which later shifted to the general fund. Following extensive analysis, the U.S. Attorney’s Office concluded that no further charges could be pursued.

Napier has also approached the Pima County Attorney’s Office, seeking a review to determine if any state laws were violated. Should the County Attorney’s Office recuse itself, Napier indicated he would escalate the matter to the Arizona Attorney General.

Pima County Attorney Barbara LaWall acknowledged receiving Napier’s request and is currently evaluating the situation. She has refrained from further comment due to the ongoing nature of the investigations.

These developments follow a politically tumultuous period for the sheriff’s office, marked by Napier’s defeat of then-Sheriff Chris Nanos in 2016, and Nanos’s appointment after Sheriff Clarence Dupnik’s retirement in 2015.

The scrutiny surrounding the department’s financial integrity continues, as the FBI and local officials aim to ensure accountability and restore community confidence in law enforcement operations.
