Answer
Dustin,
If your engine completely ran out of oil, your oil light should have come on and your engine temperature gauge would have gone into the red and overheated.  Without oil and the high heat, that can cause your engine to seize up and not be able to crank.  That pop you heard may have been caused by a backfire due to a clogged exhaust.  It may have caused your starter motor to lock up.  

Have your mechanic inspect the engine to determine if it's seized.  This can be pretty easily tested by removing the spark plugs and manually turning the crankshaft.
Good luck!
