There would be ample evidence of where this happened - I don't understand why you don't know what happened.
If someone took it off the car (vanadlism), where the oil filter was taken off would have a HUGE puddle of oil in it, both from the filter coming off, and from the oil being pumped out.
Was their oil in any parking spot you were at - home? work? school?
If the oil came off while you were driving, you would have left a large trail of oil behind you - have you checked the raods you drive on to see if you can find an oil slick, and maybe even the filter?
There is evidence out there - go find it!!!!
