Pursuant to the provisions of Chapter 143 of the Texas Local Government Code, Section
143.054, and Rule 8, Rules of Procedure for the Firefighters’, Police Officers’
Emergency Medical Service Personnel’s Civil Service Commission, Sergeant Sin and I have
agreed to a voluntary demotion two ranks, to the civil service classification of Police Officer.
This demotion is effective today.
This double-demotion is based on Sergeant Sin violating Civil Service Commission Rule
10.03, which sets forth the grounds for disciplinary suspensions of employees in the
classified service, and states:
No employee of the classified service of the City of Austin shall engage in,
or be involved in, any of the following acts or conduct, and the same shall
constitute cause for suspension of an employee from the classified service of
Violation of any of the rules and regulations of the Fire
Department or Police Department or of special orders, as
This double-demotion is based on the following facts:
On Sunday, April 28, 2019, at approximately 5:11 P.M. Austin Police Department (APD)
Baker Sector Officers were dispatched to a Crash Hotshot that involved multiple vehicles at
4801 Plaza on the Lake, Austin, ~ ~Qp
;y,_Tcw,. It~was later reported a female was
trying to run away from her husband, who was driving a vehicle, and subsequently hit her
with that vehicle. Prior to APD Officers arriving at the initial scene, the husband fled into a
wooded area, and a coordinated search ensued. Shortly after, the husband was found in the
wooded area by officers hiding in a brushy area. Both officers discharged their firearms,
fatally wounding the husband. During this incident, Sergeant Sin admits that he failed to
perfoi-m his duties in a satisfactory manner.
By these actions, Sergeant Sin violated Rule 10.03(L) of the Civil Service Rules by
violating the following rules and regulations of the Austin Police Department:

**For clarification purposes, I am sustaining subpart (b) for Sergeant Sin shirking
his duties in the case of danger, not for exhibiting cowardice in the case of danger.
