The 29-year-old was sitting in his car in plain clothes outside the Downey Police Department when he was shot and killed in a targeted attempted robbery in November 2015.

"He lived life as a shining example for others to emulate," Downey Police Chief Carl Charles said during the ceremony.
Gavlez was a Marine veteran who served two tours and had been a police officer for five years.
His career dream was to become a K-9 officer, which is what he had just finished training for when he was shot.

"On Nov. 30, 2015, the department posthumously appointed Officer Galvez to the position of K-9 officer with the associated call sign of 5-king," Charles said.
At the Wednesday ceremony, family members were presented with a folded American flag and watched as a plaque was dedicated to Glavez on the Fallen Officer Memorial.
Days away from the one year anniversary of his murder, the pain was still fresh, but those gathered tried to focus on how Galvez lived rather than his death.
"Let us remember to teach our children that we do not have to turn on the television to find our heroes. They are before us," said Downey Mayor Alex Saab.
