Possible scenario: cpu is stuck to heatsink with thermal paste and instead of 
- running the PC for a while to heat up the thermal paste
- pulling straight upward
- wriggling the cooler slightly 

somebody twisted the cooler including the cpu out of the socket.

Not gonna lie, kinda impressive…

Sometimes it gets stuck even if you heat it up a bit beforehand. I got the stuck cpu of doom when I was switching them out and it scared the shit out of me (literally ran a benchmark to get it to max heat beforehand)
