SAN JOSE, Calif. (KRON) — The Santa Clara County Coroner’s Office identified two of the three people killed in a double murder and suicide carried out in an upscale San Jose apartment complex.

The coroner’s office told KRON4 on Tuesday that two of the people killed were Erica Pantoja and Marco Carral Duran. The third person’s identity will be released after his family is notified.

San Jose police said the triple shooting began as a “domestic dispute” between a husband and wife in a parking area for Crescent Village Circle apartments on June 12.

Duran, 23, was working nearby as a security guard.

Duran saw an altercation escalating between Pantoja and her husband in the parking area just before 1 a.m., according to investigators.

The husband shot the security guard when the guard attempted to intervene, according to police. The husband then shot his wife and shot himself, Sgt. Christian Camarillo said.

The couple’s six children were home inside one of the apartments at the time, according to investigators.

Someone called 911 at 1 a.m. reporting a shooting with multiple victims.

Pantoja, her husband, and Duran were pronounced dead at the scene. Police said they determined that the husband died from a self-inflicted gunshot wound.

“The motive and circumstances surrounding the incident are under investigation,” Camarillo said.

Duran’s family member, Fernanda Duran, wrote on a GoFundMe page, “Amidst the emotions we are having to learn details of this shooting, why, how, not us. This all occurred during his work shift as a security guard. He was only trying to break up a domestic dispute. He is a hero who protected 6 kids from the shooter.”

“His smile and laughter filled voids for many. He was a shoulder to lean on while our mother raised the four of us on her own. Marco was our oldest brother, and he dreamt of being a UFC Champ; he trained, watched UFC fights, and was determined. He was training at the American Kickboxing Academy, but when Covid hit, he put his dream aside to be able to provide for our family. Today, our family’s life and the life of our loved ones has come to a screeching halt, and we are all in shock,” Fernanda Duran wrote.

There have been 16 homicides in San Jose this year.
