“He’s always been a protector,” Perez’s brother, Miguel, said. “He’s been a protector of his family, whether it was his mother, his siblings, neighborhood, against bullies. Police work is always what he wanted to do. He loves dogs, loves dogs and he loves more dogs.”

Perez is survived by his wife and three children. A GoFundMe has been set up to help the family.

Perez was 49 years old.
