A Venezuelan national is accused of fatally stabbing a man at a hospital in sanctuary California, and federal officials are once again calling attention to policy failures that allow illegal immigrants to roam free in the country.
Wilfredo Jose Tortolero-Arriechi, 34, was charged with murder following the horrific attack on a social worker inside a San Francisco hospital in December. He is in the country illegally and had previously been encountered and released by Border Patrol.
Last week, the U.S. Department of Homeland Security brought renewed attention to the case and requested local authorities not to release the suspect from jail. That’s because many California communities refuse to cooperate with U.S. Immigration and Customs Enforcement or honor immigration detainers.
ICE lodged a detainer request for Tortolero-Arriechi on Dec. 11, 2025, following his arrest for the stabbing attack that claimed the life of 51-year-old Alberto Rangel, a social worker at the hospital.

Federal immigration officials have pointed to California’s sanctuary policies and the Biden administration’s border decisions as contributing factors in another senseless murder.
“If it weren’t for the Biden administration’s reckless open-border policies, Alberto Rangel would still be alive,” said Acting Assistant Secretary Lauren Bis. “We are calling on Governor Gavin Newsom to commit to not releasing this murderer from jail.”
In the weeks before the stabbing, Tortolero-Arriechi reportedly threatened his doctor and staff at the hospital. He now faces charges for homicide and use of a deadly weapon and has been behind bars at the San Francisco County Jail.
Initial news reports from the sanctuary community of San Francisco, including a news release from the District Attorney’s office announcing the charges, failed to mention Tortolero-Arriechi’s immigration status.
According to various reports, Tortolero-Arriechi allegedly attacked and repeatedly stabbed Rangel on Dec. 4, 2025, at Zuckerberg San Francisco General Hospital.

Rangel died two days later on Dec. 6, prompting the San Francisco District Attorney’s Office to upgrade the charges from attempted murder to murder on Dec. 8.
According to authorities, Tortolero-Arriechi went to Zuckerberg San Francisco General Hospital Ward 86 to speak to a doctor and had a concealed knife with him.
KRON4 News reported Ward 86 serves as the largest clinic in the San Francisco Health Network for AIDS and HIV-infected patients, as well as low-income and immigrant patients. Rangel was employed as a social worker by UCSF Health at ZSFG, city officials said.
The District Attorney’s office said Tortolero-Arriechi appeared “calm and engaged in a conversation with a social worker and was advised to leave.” Then, as he walked with Rangel to the elevator, Tortolero-Arriechi “suddenly grabbed the victim from behind and stabbed him numerous times,” prosecutors wrote.
The San Francisco Sheriff’s Office also shared details of the attack on social media, noting the victim sustained multiple stab wounds, including injuries to the neck and shoulder. Rangel was transported to the operating room in critical condition but later died.
KRON4 reported Tortolero-Arriechi was reportedly a regular patient at Ward 86. He was at the hospital for a scheduled appointment and had previously made threats to the doctor.
“While providing security for the doctor, our sheriff’s deputy heard a disturbance unfolding in the hallway involving the suspect, who was attacking a social worker,” according to the sheriff’s office statement. “The deputy intervened immediately, restraining the suspect and securing the scene.”
But Rangel’s co-worker, Maddy Auble, previously told KRON4 that she heard screaming outside her office in Ward 86 and ran out to see what was happening. “He murdered my co-worker in front of all of us,” she said. “I don’t know where the sheriff was … he wasn’t there.”
Union leaders also spoke out after the disturbing attack that led to Rangel’s death. Social workers and their union released a list of demands for outpatient, inpatient and crisis-response teams’ workplace safety.
“Our members have long sounded the alarm about unsafe conditions and chronic understaffing that put them at risk every day, as they serve as the social workers and behavioral health clinicians on the front lines of the city’s mental health crisis,” wrote Dan Russell, president of University Professional and Technical Employees, in a statement shared by KRON4 News.
Tortolero-Arriechi was taken into custody at the scene. Deputies also recovered a five-inch kitchen knife. His initial arraignment was also delayed because he was transferred to the psychiatric ward at the same hospital.
U.S. Border Patrol agents first encountered Tortolero-Arriechi in 2023. He was then released into the country by the Biden administration.
In February, ICE Director Todd Lyons sent a letter to California Attorney General Rob Bonta calling on him to “put the safety of Americans first” and honor ICE arrest detainers. The agency revealed more than 33,000 criminal illegal aliens in California’s custody have active detainers.
Despite that, DHS officials said thousands have been released. Since January 2026, California jurisdictions have declined to honor ICE detainers in more than 4,500 cases, according to the agency.
DHS officials have also said 7 of the 10 safest cities in the U.S. cooperate with ICE law enforcement.
“California’s sanctuary policies put American lives at risk,” Bis said. “Criminal illegal aliens should not be released from jails back onto our streets to terrorize more innocent Americans. If we work together, we can make America safe again.”
Gov. Gavin Newsom’s office pushed back against those allegations and said violent offenders “should be held accountable in our justice system,” Fox News Digital reported.
Since 2019, the state has coordinated the transfer of more than 12,000 individuals, including those convicted of serious and violent crimes, into ICE custody, the governor’s office said.
“Allowing someone to evade responsibility simply by being deported undermines the rule of law and completely disrespects the victims harmed by that crime,” the Newsom spokesperson told Fox News Digital. “Our focus must always be to ensure those who commit violent acts face their consequences here.”
However, criminal suspects are often released while awaiting trial, so they can move around and reoffend or flee the state or country. They also create more burdens for California’s already over-taxed residents by spending years in the criminal justice system.
