Officer Jonah Hernandez: Attack, Bystander Case, and NM Law Changes

Officer Jonah Hernandez was a 35-year-old Las Cruces Police Department patrol officer who was stabbed to death on February 11, 2024, while responding alone to a trespassing complaint in Las Cruces, New Mexico. His killing was the first on-duty death in the department’s 96-year history, and it set off a public reckoning over mental health care, repeat-offender sentencing, and police staffing in southern New Mexico.¹

What Happened on February 11, 2024

Around 4:55 p.m., Hernandez arrived at 335 South Valley Drive to answer a trespassing call. The property owner had told 911 that a man kept coming onto her land, that her husband had already asked him to leave, and that syringes had been found on the grounds. She wanted an officer to issue a formal warning.²

Hernandez approached 29-year-old Armando Silva, who was sitting under a covered structure on the property. Body camera footage shows Hernandez asking whether Silva was the person who had called. Silva stood up, pulled a large kitchen knife, and lunged at the officer. Hernandez turned to run and fell. Silva stood over him and drove the knife down repeatedly. Hernandez got briefly to his feet before collapsing again.³

A 29-year-old bystander named Issiah Astorga saw the attack from nearby. He later said Silva was “in complete control of the altercation” and that Hernandez was “bleeding severely from the neck.” Astorga retrieved a handgun from his vehicle, approached, and yelled at Silva to stop. When Silva turned and advanced on him, Astorga fired, killing him. Body camera audio captured three shots in close succession, then a fourth. Astorga crouched over Hernandez and told him to “stay with me,” while another civilian used the officer’s radio to call for help.⁴⁵

A second officer reached the scene at 4:59 p.m. Hernandez was taken to MountainView Regional Medical Center, where he died that evening.¹

Who Jonah Hernandez Was

Hernandez was born in El Monte, California, and grew up in El Paso, Texas, graduating from Americas High School in 2006. He joined the Las Cruces Police Department in June 2022 and had served as a patrol officer for roughly two years when he was killed. He left behind a wife and two sons.⁶⁷

The Attacker’s Record and Mental Illness

Las Cruces Police Chief Jeremy Story said Silva had “a long history of violent crime and mental illness,” and called the record “just one more agonizing reminder of the brokenness of the New Mexico Criminal Justice System.”⁸

Silva’s prior cases included a 2013 misdemeanor marijuana possession charge that resolved with a deferred sentence; a 2015 kidnapping and aggravated battery against a household member that drew four years in prison and two years of parole; a 2019 methamphetamine possession charge dropped in November 2022 when witnesses were unavailable; and an April 2023 battery charge that was dismissed. Court records attributed that final dismissal to a missed appearance by a Doña Ana County deputy, but Sheriff Kim Stewart said public records indicated the prosecutor had failed to appear. Silva had multiple probation and parole violations that returned him to prison more than once, and in 2019 he cut off his GPS monitoring bracelet and was found with drugs.⁸⁹¹⁰

Chief Story initially described Silva as homeless. Silva’s family disputed that. His mother, Xóchitl Hernandez, said he lived in a Picacho Avenue apartment that she and other relatives helped pay for, and his aunt, Virginia Lerma, said Silva’s mother “worked three jobs to pay for his apartment, so that he would not be sleeping in the streets.” According to his mother, Silva had schizophrenia and had stopped both his prescribed medication and his therapy appointments about three weeks before the attack. Lerma called his illness “overwhelming” and said it “controlled his life.”¹¹¹²

Xóchitl Hernandez publicly expressed “heartache for lives lost” and urged the community to “heal together,” saying Las Cruces had a “severe mental illness issue.” Mayor Eric Enriquez said, “This tragedy only signifies that we do have a problem. We will address it but right now we’re mourning Officer Hernandez.”¹²

Why the Bystander Was Not Charged

On February 27, 2024, investigators presented the shooting to the Third Judicial District Attorney’s Office. Two days later, District Attorney Gerald Byers announced that Astorga would face no charges. Chief Story released a video statement from Astorga that same day to, in the chief’s words, “head off rumors circulating in the community.”¹³

Through his attorney Luis Robles, Astorga said: “Due to the severe bleeding from the officer, I knew that the individual approaching me had a weapon. Fearing for my life, my girlfriend’s life, and the officer’s life, I fired my handgun.” He called the shooting a traumatic event he would carry for the rest of his life. In October 2025, the nonprofit The Wounded Blue presented Astorga with its “Citizen’s Award for Valor” at a banquet at the New Mexico Farm and Ranch Heritage Museum, alongside co-honoree Araceli Hernandez.¹³¹⁴

The Mental Health Gap That Framed the Reaction

Eleven days before the attack, on January 31, 2024, the Doña Ana County Crisis Triage Center closed. The closure followed a January 9 vote by the Board of County Commissioners to deny a nearly $562,000 state grant that would have funded the facility’s operator, RI International. Commissioner Shannon Reynolds said the center was “too expensive to rationalize funding” and said he preferred local organizations over the Arizona-based company. RI International’s deputy CEO, Paul Galdys, said the center served about 1,000 patients a year but needed 2,500 to break even under existing reimbursement rates, and that the grant was state-funded and required no local match.¹⁵

Commissioner Manny Sanchez later said the vote was partly a miscommunication, with commissioners mistakenly believing the existing contract ran through the end of the fiscal year.¹⁶ Silva’s aunt pointed to the closure directly, saying Las Cruces “doesn’t have the necessary resources to help the many persons afflicted by mental illness.”¹¹

What Changed After the Killing

Chief Story set three short-term priorities after Hernandez’s death: filling officer vacancies, pursuing new city ordinances, and standing up a real-time crime center.¹⁷

The LCPD Real-Time Crime Center opened in September 2025 at police headquarters in downtown Las Cruces. Built with about $2 million in local, state, and federal funding, it lets technicians pull live feeds from cameras, drones, and body-worn cameras and relay intelligence to officers in the field. Story said the facility was designed to help the department be “proactive, with information and intelligence, rather than reactive.”¹⁸ On the ordinance front, the City Council approved updates to the solicitation code in August 2024, prohibiting aggressive solicitation in public areas and restricting solicitation on certain roadways and medians.¹⁹ The department has also pushed hard on recruitment, offering up to $35,000 in combined incentives for lateral transfers and retired officers and up to $30,000 for new cadets with advanced degrees.²⁰

In Hernandez’s memory, the LCPD launched “Not in Vain” crime reduction operations. The 2025 operation, run with partner agencies from late April through late August, produced 120 felony arrests, 134 misdemeanor arrests, and more than 1,000 community interactions. A third operation was planned for spring 2026.⁷

State Legislation

In February 2026, the New Mexico House passed three public safety bills tied to the issues the case raised. Senate Bill 3 updated the state’s Mental Health Code and Assisted Outpatient Treatment Act to give law enforcement and courts clearer standards for assessing people who pose a risk of serious harm. House Bill 43, which passed unanimously, strengthened survivor pension benefits for families of police officers, firefighters, and correctional officers killed in the line of duty. House Bill 61 raised the penalty for shooting at and missing an officer to a second-degree felony and enhanced penalties for assaults on law enforcement.²¹ Governor Michelle Lujan Grisham signed House Bill 43 into law in March 2026.²²

Memorials

A public candlelight vigil was held on February 16, 2024, at Albert Johnson Park, and residents were asked to display blue porchlights in the days before the funeral.²³ Hernandez was laid to rest on February 21, 2024, after a service at Abundant Living Faith Church in El Paso. The service included full police honors, a 21-gun salute, “Amazing Grace” played by the honor guard, and a formal “End of Watch” call. A flag that had flown over the New Mexico state capitol was presented to his son, and hundreds of officers from departments in Las Cruces, El Paso, Chicago, New York, and Arizona attended. He was buried at Our Lady of Mount Carmel Cemetery in El Paso.²⁴

Hernandez was scheduled for induction into the National Law Enforcement Officers Memorial in Washington, D.C., during National Police Week in May 2025, the first LCPD officer added to the memorial.²⁵ On the second anniversary of his death, February 11, 2026, the LCPD held a private memorial with a procession from the site of his final call to department headquarters.⁷
