Teens, Booze and Guns: Gilroy Halloween Party at Council Member’s Home Turns Deadly

A 19-year-old cousin of Gilroy council member and prominent Santa Clara County Democrat Rebeca Armendariz was arrested Oct. 31 in connection with a Halloween party shooting outside her Gilroy home that left an 18-year-old dead and three other teens injured.

Update: DA declines to charge Oct. 30 shooting suspect

Gilroy police took Benjamin Calderon of Gilroy into custody in connection with the shooting death and said Nov. 1 they believed at least two shooters were involved in the early morning incident.  Investigators said they found two firearms at the scene of the shooting, as well as other evidence. Armendariz told ABC7 News that the alleged shooter is her second cousin, and that she was home at the time of the fatal shooting.

Gilroy police on Monday identified the deceased victim as Michael Daniel Zuniga-Macias, 18. All of the injured are between the ages of 17 and 19 years old, according to Gilroy police, who were called to the large party shortly before 1am Saturday morning.

A post to the Gilroy Dispatch’s Facebook page showed an invitation to a party at the Armendariz home hosted by “Ben.” It is not clear if Calderon was the host. The family home referred to as “El Rancho Las Animas” was the site of recent beer and rum drinking parties with members of the Armendariz and Calderon clans, according to social media posts.

Armendariz, who worked for 15 years as an organizer for the Service Employees International Union (SEIU), became business representative for Operating Engineers Local 3 two years ago, according to her LinkedIn profile.

Since being elected to the Gilroy City Council in 2020, Armendariz has been an ascendent political figure, serving on the Santa Clara County Democratic Central Committee. A month ago she stood beside Assemblymember Evan Low and former Silicon Valley Leadership Group CEO Carl Guardino to endorse County Supervisor Cindy Chavez for mayor of San Jose at Chavez’s kickoff event.

The city of Gilroy has a “social host accountability” ordinance that holds “social hosts and/or landowners” responsible if they “knowingly allow such loud or unruly gatherings to occur on their premises, at their residence, or at rented facilities where alcoholic beverages are served to, consumed by, or in the possession of underage persons.”

“It shall be unlawful for a person to knowingly conduct or allow a loud or unruly gathering where alcohol is served to, consumed by or in the possession of an underage person,” the ordinance reads.

  1. Regardless of what I think about the politicians involved, this is terrible and I wouldn’t wish it on anybody. However the whole kids drinking pearl clutching seems to be a joke. I got drunk at my sisters wedding when I was 13 and its far better to experience alcohol (which is more ubiquitous than guns) for the first time around your family than the alternative. My family has been partying together for 100s of years and I fail to see how this is different.

    Kids getting shot happens regularly on every weekend in large cities and is more a reflection of a deteriorating family culture than families having a party together.

    I wish all the families peace in what will be very difficult days and months ahead.

  2. You wrote, ‘ 19-year-old cousin of Gilroy council member and prominent Santa Clara County Democrat Rebeca Armendariz was arrested Nov. 30…’
    ‘Gilroy police arrested Benjamin Calderon of Gilroy Nov. 30 ‘.

  3. Rebeca is definitely Dem leadership quality. SEIU trained and completely irresponsible – booze, teenagers, guns, and partying till after 1 am. Maybe next time have a bbq, some entertainment and socializing then send everyone home at nine? It seems strange that Dems are so anti-gun and at the same time so heavily armed.

    Sarcasm aside, it is sad to see these young people killed and injured. My condolences to their families.

    One final thought: Please stop— please, no reprisals. Stop the tribalism.

  4. Armendariz lacks good judgment if she lets underage youth drink on her property even if the property is shared with another house. We expect lawmakers to follow the law — especially city councilmen breaking a city ordinance. I don’t see how she escapes liability for this.

  5. She will escape liability because she has political juice, a friendly Marxist media, and she can play the race card (usually from the bottom of the deck). Before this is over, she will become the victim. ?
