All six lug bolts broke?

Given the apparent condition of the vehicle in general, I'd say some have been broken or missing for a long time, and the vehicle was running on only some of the bolts already. It's amazing to me the number of vehicles you can find in parking lots with missing lug nuts or lug bolts.

Looks OK to me, though you can't tell that much from a night photo.
Stud ends don't look shiny, which would support your speculation except none of them look shiny, so they must have rusted post-wheel loss unless it was only rust that was holding the wheel on.
What am I missing?

To all those who say, "Never anti-seize a lug stud"......
Studs are thin and vulnerable looking to start with. Add salt, water and goons applying 450 ft/lbs of torque during tire changes and there you are!

And people tell me not to anti seize the threads. After 30+ years of car ownership, I have seen more problems by not anti seizing lug threads as opposed to anti seizing. I have yet to meet someone who anti seized their threads, kept the chamfer dry and have their lugs back out. Yet I know tons of people who have snapped wheel studs due to rust.

Well, I never say that, and always lubricate, but since I can't tell if they were lubricated or not, this incident could be a case of Lubrication causing over-torquing and fracture just as much as it could be an example of non-lubrication causing the same thing.

It would be nice to get a close up shot of the studs. I analyze stud failures for a living. Failures like this are typically due to movement of the fastened assembly, such as forgetting to tighten the lugs or using a wheel that interferes with the pilot.
Corrosion between drum and axle strong enough to prevent separation tells the story.

Could this also occur due to mismatch between the nuts and the nut-seats on the wheel?
For instance, I've seen wheels come loose when tapered-type nuts were used with ball-type seats, even though the nuts were torqued sufficiently initially.

I wonder if it had OEM or (incorrect) aftermarket rims?
And the comments of anti seize have nothing to do with this. This is not a "all the studs broke taking the lugs off", this is a vehicle that had an apparent simultaneous, catastrophic failure of 6 studs. This is an issue of poor maintenance, incorrect torque, incorrect lug nuts, incorrect rims (lug spacing, seating type, offset, etc) or some other type of failure of the studs.
