June 1, 2025 – Baldwin Park Police Department officials issue a statement from Chief Robert A. Lopez on behalf of the men and women of the Baldwin Police Department.
It is with profound sadness and heavy hearts that the Baldwin Park Police Department announces the tragic death of Officer Samuel “Sam” Riveros, who made the ultimate sacrifice while 
protecting our community.
Yesterday, Officer Samuel Riveros, Officer Anthony Pimentel, members of our Department, and assisting law enforcement agencies, responded to an extremely dangerous situation. They acted with the bravery and professionalism that define the finest in law enforcement. In that moment, Officer Samuel Riveros made the ultimate sacrifice to protect the lives of others and the community in which he served. Officer Anthony Pimentel, also in the face of danger, was injured and released from the hospital early this morning.
Today, we mourn a courageous officer, a respected colleague, and a beloved friend. Officer Samuel Riveros began his service with us as a Public Safety Trainee on April 3, 2016, and was sworn in as a Police Officer on September 11, 2016. His commitment to excellence led to his selection for the SWAT Team on July 1, 2019, where he served with honor for over five years. Most recently, he was appointed as a Field Training Officer on July 21, 2024, a testament to his leadership and mentorship.
A proud UC Irvine graduate, Officer Samuel Riveros was known not only for his tactical skills and professionalism, but for his love of snowboarding and his unwavering loyalty to the Los Angeles Dodgers. His legacy will live on through the lives he touched and the example he set.
We extend our deepest condolences to the Riveros family, his loved ones, and all who had the honor of serving alongside him.
At this time the Riveros family has asked for privacy during this tragic time.
