Longtime LAPD Sergeant Among Two Killed in Devastating Crash on 405 Freeway

LOS ANGELES — Tragedy struck the city early Monday morning when a deadly crash on the southbound lanes of the 405 Freeway claimed the lives of two people, including a respected Los Angeles Police Department sergeant. The collision forced the closure of all southbound lanes through the Sepulveda Pass for nearly 11 hours, causing massive traffic disruptions across the region.

The Incident

According to the California Highway Patrol, the fatal accident occurred around 2 a.m. near Moraga Drive. Emergency responders arrived to find a marked LAPD vehicle heavily damaged on the driver’s side door, alongside several other wrecked vehicles scattered across multiple freeway lanes.

One victim was declared dead at the scene, though authorities have not released the individual’s identity. Tragically, Sgt. Shiou Deng — a 26-year veteran of the LAPD known for his dedication to community service — succumbed to his injuries later at the hospital.

A Dedicated Officer and Community Servant

LAPD Chief Jim McDonnell addressed the media hours after the crash, confirming Sgt. Deng’s death and honoring his legacy.

“Sgt. Deng was a deeply respected leader within our department and a trusted protector of our communities,” McDonnell said. “His loss is immeasurable, and the grief we feel is shared not only by the men and women of the LAPD, but by the entire law enforcement family and the residents he served so faithfully.”

Sgt. Deng, who worked out of the West Los Angeles station, spent much of his career serving in the mental evaluation unit — a role critical to bridging law enforcement and mental health support.

Authorities revealed that Deng was assisting at the crash scene when he was fatally struck by a passing vehicle after exiting his patrol car.

Community and Official Reactions

The news of Sgt. Deng’s passing sent ripples of sorrow across Los Angeles. Mayor Karen Bass, in a heartfelt social media post, expressed condolences to the sergeant’s family and colleagues.

“This morning, I met with officers at the hospital who described him as caring and selfless. His last act was one of service — putting the safety and wellbeing of others above all else,” Mayor Bass wrote.

In honor of Sgt. Deng, flags on city buildings were ordered to be lowered to half-staff. California Governor Gavin Newsom followed suit, announcing flags at the State Capitol and Capitol Annex Swing Space would also fly at half-staff.

Impact and Aftermath

A third person involved in the crash was rushed to the hospital, though details regarding their condition remain unavailable.

The 405 Freeway, a major artery in Los Angeles, was fully reopened by approximately 12:30 p.m., following nearly 11 hours of lane closures and significant traffic delays.

A solemn procession accompanied Sgt. Deng’s body from Ronald Reagan UCLA Medical Center to the Los Angeles County Medical Examiner’s office, drawing officers and community members alike who wished to pay their respects to the fallen hero.

The Broader Context

This heartbreaking incident underscores the dangers law enforcement officers face daily — not only from criminals but from the hazards inherent in protecting and serving the public on busy highways and unpredictable situations.

Sgt. Deng’s death is a poignant reminder of the sacrifices made by those who stand as the first line of defense in keeping communities safe.

Conclusion

As Los Angeles mourns the loss of Sgt. Shiou Deng, the city honors a man whose career was defined by compassion, courage, and an unwavering commitment to service. His legacy will live on through the lives he touched and the example he set for law enforcement officers across the nation.

The LAPD and the city of Los Angeles extend their deepest sympathies to Sgt. Deng’s family, friends, and fellow officers during this difficult time.
