Zamora’s mother, Agnes Mantanane, shared on Facebook a heartbreaking and emotional statement regarding her son’s death: “Oh Lord I have neither the words to speak nor the strength to stand and I come to you grief-stricken because of this terrible tragic loss. All I can cry is Abba Father, All I can ask is why. Help me to come to terms with what has happened to my son Joey.”

The motive for the shooting is not known. However, police have arrested Anthony Gregory Mendiola in connection with the incident. He was arrested on allegations of reckless conduct, family violence, possession of a firearm without valid identification, and unlawful transfer of a firearm.

GPD Spokesperson Sgt. Paul Tapao reports that CID detectives were able to locate and seize a firearm and other evidence. Their investigation continues as GPD officers went back to the crime scene. They were seen canvassing Chalan Tutujan Drive and the nearby streets appearing to be looking for something.

At the crime scene this morning, PNC talked with neighbors who indicated that the home in which the incident occurred is occupied by an elderly woman. One neighbor, who wishes to remain anonymous, stated that it was shocking to hear about the shooting, further stating that the neighborhood is quiet and peaceful.

Another neighbor told PNC that the incident raises concerns about the safety of the area.

Zamora’s death remains classified as a death investigation pending the results of an autopsy.

Mendiola was charged in the Superior Court of Guam this afternoon.
