San Bernardino County – Amid the roar of engines on a busy freeway, a single act of bravery brought a dangerous chase to a screeching halt, saving lives in the shadow of tragedy.
A Deputy’s Final Call Turns Deadly
Picture this: a routine response to a domestic violence report spirals into chaos in seconds. San Bernardino County Sheriff’s Deputy Andrew Nunez arrived at a home in Rancho Cucamonga, only to face gunfire from the suspect, Angelo Jose Saldivar. The shots were fatal, leaving Nunez, a father and husband, gone too soon. His pregnant wife and young daughter now carry the weight of that loss.
The incident unfolded on October 27, 2025, shaking the department to its core. Saldivar didn’t stick around; he grabbed a motorcycle and bolted, sparking a pursuit that would test everyone’s limits. News of the shooting spread fast, drawing support from across the region as the hunt intensified.
The Chase That Gripped the Freeway
Saldivar hit the 210 Freeway, weaving through traffic at speeds topping 150 mph. Sirens blared as pursuing officers tried to close the gap, but the suspect’s reckless riding made it a nightmare. Drivers pulled over in fear, the freeway turning into a high-stakes racetrack under the afternoon sun.
For several tense minutes, the chase stretched on, with Saldivar dodging attempts to box him in. The situation screamed danger – not just for the officers, but for innocent commuters caught in the middle. Everyone watching knew one wrong move could end in disaster.
Off-Duty Hero Steps Into the Fray
That’s when Detective Shaun Wallen entered the picture. Off-duty and driving his own vehicle, Wallen spotted the unfolding pursuit and acted without hesitation. He positioned his car perfectly and executed a precise maneuver, knocking Saldivar from the motorcycle in a controlled takedown. The suspect crashed, was apprehended, and the threat ended right there on the asphalt.
Wallen’s quick thinking prevented further harm, turning a potential multi-vehicle pileup into a safe capture. Facing charges like murder and assault, Saldivar now sits behind bars, thanks to that split-second decision. Wallen’s move wasn’t just skill; it was pure instinct honed from years on the job.
A History of Bravery Under Fire
Wallen isn’t new to high-pressure moments. Back in 2015, he earned a Public Safety Medal of Valor for his role in responding to the San Bernardino terror attack. That day, he helped secure the scene amid gunfire and fear, showing the same calm resolve that defined his recent actions.
Over a decade later, his track record speaks volumes. Colleagues describe him as steady and selfless, the kind of officer who steps up when others can’t. This latest feat adds another chapter to a career built on protecting the community, no matter the risk.
Honoring Courage in the Line of Duty
On November 22, 2025, Wallen received official recognition for his heroism. At a ceremony, Sheriff Dicus and department leaders praised his actions as a model of dedication. The event highlighted not just Wallen’s role, but the broader spirit of the force amid grief over Nunez’s death.
Family, friends, and fellow deputies gathered to celebrate, turning sorrow into a moment of unity. Awards like this remind everyone of the human side of policing – the risks taken daily to keep streets safe. Wallen’s story inspires, proving one person’s boldness can shift the outcome.
