Incident

Sergeant Primitivo Marquez-Alejandro was shot and killed while checking on two youths wearing ski masks. Sergeant Marquez-Alejandro and his partner were driving along road PR-175 near the community of Villa Margarita in Trujillo Alto around 8:30 p.m. when both saw two people wearing ski masks. When they told the suspicious youths to stop, one of the suspects pulled a gun and started shooting at the patrol car, hitting Sergeant Marquez-Alejandro, and causing a fatal arterial wound. He was not wearing his bulletproof vest at the time. His partner and other neighbors transported him to a nearby hospital where he was pronounced dead on arrival. Sergeant Marquez-Alejandro had served with the Puerto Rico Police Department for 16 years and was assigned to Precinct 172 North Trujillo Alto. He was also a U.S. Army Special Forces veteran who worked as a Guerilla Warfare Instructor. He is survived by his wife and two sons. Just 11 months before this incident, his brother, Officer Angel Luis Marquez-Rivera was shot and killed while two men tried to rob a convenience store in Rio Piedras, Puerto Rico.

I served 1985 to 1993. You served too, before the badge - different uniform, same idea. You go where you are sent and you do not get to pick the call.
Sergeant Marquez-Alejandro gave the Puerto Rico Police Department 16 years.
Thank you for your service to the San Juan community, and for your service before it. Gone but never to be forgotten.
Rest easy, brother.
