My News LA is reporting that a man was killed riding a bicycle in Calabasas Saturday morning.

The victim, identified as 37-year old Marvin Cortez, was struck by a 25-year old Calabasas man while riding on the wrong side of Stunt Road, south of Mulholland Highway, around 9:25 am.

Cortez was reportedly riding north in the southbound lane when the driver rounded a blind curve, and crashed into him head-on.

He was taken to a hospital, but died in the ambulance before he arrived.

Stunt Road is a popular route for road cyclists in the hills between Malibu and Calabasas; it’s possible Cortez cut the corner while descending, and was in the wrong spot at the wrong time.

There appears to be some confusion about where he is from. The story leads off by calling Cortez a Los Angeles man, but concludes by saying the Los Angeles County Medical Examiner did not disclose his city of residence.

This is at least the 18th bicycling fatality in Southern California this year, and the fifth that I’m aware of in Los Angeles County.

Update: BikeLanesLA casts doubt on the initial reports, pointing out that it’s unlikely Cortez would have crossed the rumble strips at the center of the roadway. 

Update 2: A crowdfunding campaign has been established to raise funds to help pay memorial expenses for Cortez. As of this writing, it has raised over $27,000 of the $35,000 goal.

Here is how Melanie Gideon, who established the campaign, describes him.

Marv found his greatest joy in the simple, beautiful things—riding his bike like the world depended on it, sharing quiet moments with those he loved, and making everyone around him feel seen, heard, and cherished. Whether it was through his endless jokes, his goofy grin, or the calm comfort of his silent presence, he had a rare gift: he made life feel lighter, even on the heaviest days.

He was the small, funny guy in the room—the one whose energy made everyone feel at home. He didn’t need the spotlight to shine; he was the reason the room was warm in the first place. Marv was the kind of friend who’d sit with you for hours, say nothing, and still make you feel more whole just by being there. He always showed up—reliably, gently, and fully himself.

And he found his greatest love in Johanna. Their time together was filled with deep connection, laughter, and shared joy. It was a love that grounded him and made his vibrant spirit even brighter.

Update 3: A witness to the crash contradicts the original report.

Kate says she was hiking with two friends on the Calabasas Peak Trail, and was just above the trailhead when they all heard a loud engine reverberating through the canyon, even before they saw a black American muscle car roaring south towards the ocean, “like it was on a racetrack.”

They were alarmed by the speed he was traveling at, then moments later they heard a loud “pop” and saw debris flying through the air. 

From where they stood, they saw the car in a ravine, and watched as the driver got out and walked up to the road so he could see what he had done. 

Other bike riders soon arrived and surrounded the victim as she called 911. She saw them searching for something, possibly the victim’s bike. 

The ambulance came speeding up the roadway, yet still not as fast as the driver had been going. Then departed slowly after the paramedics unhurriedly tended to Cortez, which suggested to her that he may have died on impact. 

She isn’t sure about the speed limit, but thought it might be 25 mph due to the many switchbacks on Stunt Road, well below the speed the driver appeared to be doing before the crash. 

The location near the trailhead places it between two sweeping curves, which should have slowed the driver. That suggests it may be more likely the driver was on the wrong side, rather than Cortez, if he rounded the curve at speed. 

It’s also possible that both Cortez and the driver were in the same lane, traveling in the same direction at the time of the crash, which is the understanding Kate and her friends had, although she stresses that they can’t be sure. 

It may be that reports Cortez was on the wrong side of the road rely only on the word of the driver, who has a vested interest in blaming the victim, whether consciously or not.  

Kate also mentioned that they had said hello to a very friendly man “with brown hair and a beard” riding a bicycle, and hoped it wasn’t Cortez. 

If it wasn’t, it’s very possible he may have seen what happened, or at least saw the driver before the crash. 

And yes, Kate says she and her friends remain very disturbed by what they witnessed. As someone who counsels trauma victims, she now finds herself dealing with what she usually helps others with.

Having witnessed something like that myself, I can testify it remains troubling years later. 

My deepest sympathy and prayers for Marvin Cortez and all his loved ones. 

Thanks to Kate for sharing what she witnessed.

    Imagine a carfree route to the beach through the Santa Monica mountains
    ..

    Yeah we really need to get bicyclists off these roads, especially something like stunt road that has countless vehicles traveling, blind curves (and no bike lanes.)

    The few times I travel through these canyons a week, there is always a sense of danger being near there bikes, without a clear bike lane and these things roads it’s always been a recipe for disaster, additionally having mirrors around every sharp corner could help as well, if only a little.

      Get cyclists off? How about responsible driving. Going the speed limit, slowing down if necessary to pass cyclists safely, and looking up. You can see that in the photo in the now updated post there was no blind turn in the case of this accident, it happened in a straightaway. Consider how many motorists are involved in accidents off of Stunt Road. It’s notorious for reckless driving.

    Worth noting that the driver who killed Marvin is the only person who reported that the cyclist was on the wrong side of the road. Other witnesses have said that the Camaro was driving recklessly and speeding.

    • M Cortez says:

      I really appreciate your input J. The rider Marvin was my nephew and he was very familiar and experienced riding all the canyons and roads up there. The current narrative is that he was riding on the opposite side of road and that version is coming from the driver himself which seems that if he was driving the speed limit the accident might not have been avoided but I can’t help to think that a different outcome might have resulted. If you can email when time allows I would like to ask you a few questions. Thank you.

    There is no information about the details of this. The police report hasn’t been released- we will find out with the Cars dash cam. I wish people wouldn’t report lies and misinformation when it’s someone’s life and a family is grieving-

    This is a very tragic accident – again, “Accident”! Stunt is just a road to be enjoyed by all. Accidents occur every day, not just on popular “Stunt” roads that attract not only bicyclist and car enthusiasts, but many others as well. It is not our job to place blame (the illusion of control). We have a system in place that will take care of the legalities involved in this situation. Maybe try just feeling the sadness for a moment (acceptance), with no blame. Try feeling sadness for both people – because it is truly sad for both. We all take risks every time we leave our home – this is because life is a risk worth taking.
