How long is a piece of string? Sometimes it is - glass, nail, rivet, grit, sticking out of tire, etc. Only not taken wheel off and that was when it wasn't quick release and the cause obvious.
Whichever way you do it, wheel out or not, always check the inside of the tire all the way round. You may have picked up another piece of whatever caused the puncture and the evil puncture fairy is just waiting for you to reinflate the tube
