David Anthony Guzman Lopez was 25 when he was shot and killed during an armored-car robbery in Houston on August 29, 2016. Employed as a security guard for Brink’s Security, he was reportedly ambushed by masked assailants while guarding a bag that contained $120,000. He was shot while attempting to protect the cash.

Guzman Lopez was born in El Salvador, graduated from ITT, and is survived by parents Jose and Ive Membreno, his mother Rosa Lopez, and his fiancée Lorin Martinez. Investigators later identified the robbery as part of a broader criminal operation; authorities named Redrick Jevon Batiste as the alleged mastermind and arrested several suspects who were subsequently charged in connection with the robbery and murder.
