TAMPA, Fla. (WFLA) – 8 On Your Side told you last week that two top officials left the Hillsborough County Sheriff’s Office. Now, two more are facing internal investigations.

Some of the internal turbulence is connected to allegations of academic cheating and the hiring of a man named Robert Roush.

It came after Former Chief Deputy Anthony Collins resigned four months into his historic promotion.

“He paid somebody to do his coursework at the prestigious FBI National Academy,” Sheriff Chad Chronister said.

Collins resigned in July after his wife reported him for “academic dishonesty” and shared emails, which 8 on your side obtained. The emails show Collins corresponded with Roush to complete his coursework at the FBI National Academy.

One email from Roush to Collins reads: “All work in class should be done. Do we have anything else due that I may have missed?” In another email, Roush writes: “Here is our paper. It meets the guidelines and requirements without focusing too much on the personal.”

“[Collins] did apologize he said he would never do anything out of his love for me out of his respect for me to dishonor his position at the office,” Chronister said.

Now, 8 On Your Side is learning that Roush allegedly had contact with three other sheriff’s office officials: Colonels Michael Hannaford, Chris Rule, and former Captain Lora Rivera.

The sheriff’s office said Rivera put in her resignation on Thursday amid allegations she had paid Roush to write her captain’s project for her. However, this was before an internal affairs investigation could be started. Rivera was the Deputy Division Commander for the agency’s Professional Standards Bureau.

According to the sheriff’s office website, Col. Hannaford supervises the Department of Patrol Services, while Co. Rule overseas the Department of support Services.

HCSO said years ago, they allegedly hired Roush for help. For Hannaford, that was for writing a report relating to his captain’s project and for Rule, a research paper for a class with Florida Department of Law Enforcement.

At this time, a sheriff’s office spokesperson said both Hannaford and Rule are under an internal affairs investigation to determine if the communication with Roush violated any of the agency’s policies. They have not been suspended.

Chronister shared this message: “Our community can be reassured that when we receive any allegation of misconduct by a member of our Office, I will not stop until I uncover any and all wrongdoing and that the consequence will be swift regardless of the individual or position they hold.”

8 On Your Side reached out to Roush but has not yet heard back.

On top of all of that, HCSO’s District Commander of Court Operations, retired on Thursday. HCSO said “upon notification of an internal affairs investigation, unrelated to any cheating on FBI coursework, into Major James Jackson, he retired. Due to the ongoing investigation, we can not provide further comment.”
