San Francisco identified the 64-year-old man who was hit and killed early Sunday morning at the intersection of 16th Street and Rondel Place, an alleyway near Valencia Street.
The man was identified on Tuesday as Ronald Duncan, a San Francisco resident, by the medical examiner. Police earlier said Duncan was already lying in the roadway when he was struck.
Officers responded to “a collision between a vehicle and a pedestrian” at approximately 2:43 a.m., the department stated.
While the driver remained at the scene, police said, paramedics transported the victim to a nearby hospital, where he succumbed to his injuries.
Duncan had lived in San Francisco all his life, a relative told Mission Local.
The collision brings the total number of traffic-related pedestrian deaths in San Francisco this year to 22, according to local nonprofit Walk San Francisco, compared to 18 in 2023. A total of 33 people have been killed in traffic incidents on San Francisco roads so far this year.
There have been a disproportionate number of pedestrian fatalities along 16th Street, Walk SF reported. Three other people have been killed within the four-block stretch between Valencia Street and Harrison Streets in the last four years.
A decade ago, San Francisco outlined “Vision Zero,” a plan to prevent severe and fatal traffic crashes. “While important progress has been made to redesign our streets to prioritize safety,” Walk SF executive director Jodie Medeiros said in a statement today, “these all-to-common tragedies continue to remind us of how far San Francisco still has to go.”

Unfortunately not an instance where Vision Zero measures or anything else could have mitigated this death. The person was lying in the road, in the dark, at approximately 3 in the morning. Closing time indeed!
I’m withholding judgement until that is independently confirmed.
It’s unfortunately really common for official claims about traffic crashes to include victim-blaming details that turn out to be false. For example, after a pedestrian was hit and killed at Parnassus and Stanyan in Cole Valley, the SFMTA director, Tumlin, said that the pedestrian was crossing against the walk light. But there is no walk light at that intersection.
Ronald unfortunately isn’t here to give us his version of the story, and it’s possible that the police statement is a mistake due to a game of telephone, or a fabrication due to a cop being sympathetic to the driver of the car.
Even if the “already lying in the street” story were to turn out to be true, 16th Street is a problem. There have been numerous deaths and serious injuries within a few blocks of here in recent years, including at Valencia and at Bryant.
Not specific to 16th Street, just normal upkeep and how you think they’d find the resolve to run this city:
The street lighting is inadequate – way too dim and lacking at crosswalks. Plus, tree trimming is way behind. There’s no shortage of streets where the canopies block the street lighting.
With all the “Vision Zero” pontification, you’d think these kinds of basics was getting managed and on a routine basis, but apparently not.
The Mission has effectively been without a district supervisor for at least the last two years. We need an advocate in City Hall, someone to pay attention to the street conditions–lighting, trees, and impaired people lying or loitering in the streets. What is Jackie Fielder’s plan for the district?
Jackie Fielder? Following her campaign showing at El Rio, we’ll have to assume she’ll blame Wall Street until we hear otherwise.
“the man was already lying in the roadway before he was struck”
— not a pedestrian.
Was this a “pedestrian” or someone lying in the street ????
“He owned a bicycle so he was a cyclist, rheeee!”
“a disproportionate number of pedestrian fatalities along 16th Street”.
Because, chaos, drugs, double-parking,
There’s this fellow posted in his black SUV at the Wells Fargo branch at times, handing out flyers for addicts to run over to the guy with the stash. Could that have something to do with it?
Did anyone else see the guy who must have thought he was auditioning for the US Olympic Break Dancing team in the middle of 16th & Valencia, yesterday afternoon at around 4:15? He had some impressive moves, but I thought he was a goner for sure when he made a leapt out in front of a MUNI bus and did the splits. When I saw this headline I thought this article was about that guy before I clicked the article and saw the incident took place in the wee hours of the morning.
@Foggy, that was a great description! I didn’t see it, but sounds like an ‘only in SF’ moment that happens here all the time! Crazy.
We basically give out 3X the funds that surrounding couties give to homeless, then they use that money for drugs. And then get killed lying on the street in the dark. Yup, pretty sure that’s what happened. We need to stop funding the homeless industrial complex and reward results.
Hopefully new leaders can get this done. (Not betting on Jackie Fielder to do squat though).
Too many cars in the city.
Too many people
Too many people afraid of cars pretending to be political or worse, being political.
Pretty misleading headline – the person was laying in the roadway at 2:00 a.m., not even at a marked intersection. Let’s spare a thought for the poor driver who ran over him, it’s the kind of horrible accident that any of us could have been involved in!
Facts don’t stop them from wanting to put in a bike lane.
Remember the elderly woman who hit the gas instead of the brake, killing 4 in the West Portal MUNI stop? Well the only solution to that problem was confusing 1-way streets and no turn signs, obviously. The SFMTA is staffed entirely with geniuses. Here’s hoping Dan Lurie guts that dept to the studs.
He was lying in the street. Vision Zero WalkSF types want to repave the district now.
Big problem in SF is that pedestrians disregard traffic and safety and are defiant and testing of vehicle traffic. There is also a lot of mental health cases on the streets.
Techies driving, techies crossing the streets. Neither takes eyes off phone.
