In the interest of informing the public following the February 10, 2015 Pasco Police-involved shooting, this page has been set-up to act as a “clearinghouse” of information and resources from the City of Pasco.


An officer-involved shooting occurred on February 10, 2015 in the area of 10th Avenue and Lewis Street which resulted in the death of Antonio Zambrano-Montes. A detailed account of the events of February 10 can be found in this release from the Franklin County Prosecutor's Office.  Officers involved in this incident were:

In accordance with department policy, the officers were immediately placed on administrative leave pending the outcome of the Tri-City Special Investigations Unit (SIU) and internal investigations.
The Tri-City Special Investigations Unit conducted the criminal investigation of this incident. The purpose of the SIU is to investigate officer-involved incidents that occur within Benton and Franklin Counties which involve great bodily harm or death. The SIU conducted a criminal investigation to develop relevant information to allow a determination by the Franklin County Prosecutor's Office of the presence or absence of criminal liability on the part of those involved in the incident. The Kennewick Police Department led this SIU investigation with a total of 15 investigators from the following agencies: Kennewick Police, Richland Police, Benton County Sheriff, Franklin County Sheriff, and the Washington State Patrol.  Please note that the Pasco Police Department was not part of the SIU investigation. 

Investigation Timelines

Department Response

The Pasco Police Department has worked with its partners and initiated efforts to better serve our residents.  The following are some examples; for a more detailed report on changes in the year following the shooting, read this February 2016 report from the Department.
  • The Department has obtained State Accreditation.
  • Exploring best-practices from police chiefs around the country by having the Police Executive Research Forum (PERF) conduct a review of policies and training of the Department.
  • Participating in the Latino Civic Alliance's Community Visioning Project to better connect law enforcement and the community. 
  • The Pasco City Council, in the June 6, 2016 meeting, approved a pilot program to equip the Department with body cameras. The Department is working to expand the program to all patrol officers.
  • The Department has adopted additional review criteria that will aid in the examination of force and the training of officers, including cataloging detailed records of Use of Force incidents.
  • Improving communication of the process for police complaints
  • Expanding Crisis Intervention Training (CIT) to more officers. The Department’s goal is to give 80% of officers CIT training by the end of 2016.
  • In response to a request for assistance from United States Attorney Michael C. Ormsby and Pasco Police Chief Robert Metzger, the U.S. Department of Justice's Office of Community Oriented Policing Services (COPS) announced in May 2015 it was offering technical assistance and training to the Pasco Police Department. 
  • Participation in the DOJ’s Community Relations Service process. 
  • Coordinating regular meetings with local clergy, specifically Latino churches, to improve relations and understanding.
  • The Department was the first agency in the area to implement a citizen academy, and, in 2016, launched a Spanish language-only academy.
  • Implementing social media (Facebook and Twitter) sites that help improve communication with the community, and launching Spanish language versions.
  • Expanding recruitment efforts, focusing on individuals who appreciate serving and reflect diverse communities. The Department encourages bi-lingual applicants, and has created a bi-lingual civil service recruitment list.  The Department continues to offer pay bonuses for officers proficient in Spanish.  These efforts have increased the bi-lingual staff. 
  • In conjunction with the COPS office to help open lines of communications and problem-solving with community members, the Department has started “Coffee with a Cop".  "Coffee with a Cop" brings police officers and the community members they serve together in a neutral & casual setting to discuss issues and learn more about each other.
  • Cooperated with the Washington State Commission on Hispanic Affairs that held listening sessions in spring 2015 at Columbia Basin College for members of the public to speak to local, state, and federal officials about the shooting.  The Commission, along with members of the City Council and the Department of Justice Community Relation Service (CRS), also held a Hispanic Community Forum in April 2015, hosted by St. Patrick's Parish in Pasco.
This unfortunate incident has caused concern within our community, and the City of Pasco and Pasco Police Department appreciate the continuing efforts of the Department of Justice, local community leaders, and residents to achieve a better understanding of the challenges we face together.
