Controversies
In July 2018, clerk Erika Romanowski was charged with federal obstruction of justice and making false statements to federal investigators. She was alleged to have disclosed sensitive law enforcement information to two "personal associates" who were targets of a federal investigation into a large-scale, drug trafficking organization. Romanowski also allegedly lied to Federal Bureau of Investigation agents when questioned, and harmed their ongoing investigation. Her prosecution is considered part of the U.S. Attorney’s public corruption initiative.

In May 2018, Deputy Donald Modrick was charged with theft, unsworn falsification and obstructing the administration of law after stealing $10,000 from a defendant. Modrick allegedly collected money without following any procedure and had checks written out in his name, which he then cashed for personal use. He was terminated by the Sheriff's Office.

Fallen officers
Since the establishment of the office, seven members have died in the line of duty.
