Officer Jon Yuen: Closed Internal Affairs Case-Clearwater Police Department 

DATE: February 14, 2020

Office of Professional Standards Investigation #IA2019-012

Involved Employee(s)

Sergeant Jonathon Yuen has been with the agency for 14 years.


Sergeant Yuen was made aware of an excessive force allegation involving an officer under his supervision. It was alleged that Sergeant Yuen took improper supervisory action after learning of the incident. In addition, it was alleged that Sergeant Yuen was untruthful when he notified his lieutenant of the issue. It was further alleged he was untruthful when interviewed as a witness by the Office of Professional Standards concerning his actions for the excessive force investigation and again when he was interviewed as the subject of the subsequent internal investigation. The appropriate general orders for the allegations are as follows:

Supervision (212.07)   Supervisory personnel (including acting supervisors) shall properly supervise subordinates, refer disciplinary charges, and take appropriate disciplinary action when necessary in accordance with department procedures.

Untruthfulness (213.47) – Employees are required to be truthful at all times to supervisors, subordinates, or other city employees whether under oath or not.

Untruthfulness During Sworn Statements (213.48) – Employees are required to completely and truthfully answer all questions while giving sworn statements during internal investigations or any other authorized or official proceeding.

Officer Jon Yuen Disposition

Based on the facts documented in the administrative investigation, the Discipline Review Board sustained the allegations against Sergeant Yuen.

Discipline/Corrective Action

In accordance with progressive discipline guidelines, Sergeant Yuen received a 5-day suspension and was demoted from the rank of sergeant to the rank of officer.

Clearwater policeman Jonathan Yuen was one of the first officers on the scene the night my son Kyle died under very suspicious circumstances at the apartment of his father, Tom Brennan, on Friday, February 16, 2007. At the time, Officer Yuen had been with the department for only eighteen months. He’d been hired right out of college. Despite this fact, however—and despite the fact that higher-ranking officers were present at the time—Yuen was placed in charge of the crime scene.

Normally, one would expect a rookie cop to follow police procedures by the manual. One would expect a young officer to try really hard, to be attentive to every last detail. In reading other Clearwater Police Reports, for example, you’ll find an amazing amount of detail. Crime scene details are extremely important. Even the tiniest bit of information, of course, can be the determining factor in a criminal investigation. People have been convicted because of tiny details. And, of course, people have walked away from criminal acts because of the lack of a tiny detail.

In the Clearwater Police Report regarding my son’s death, Officer Yuen’s one-page narrative of the events of February 16/17 is remarkable for its inattention to detail. Later, when Yuen was deposed by attorney Ken Dandar—the lawyer representing the Estate of Kyle Brennan—his brain fog surrounding the details of that evening is incredibly suspicious.
