You have to understand something very important:

Nothing was recorded about Jesus or His apostles during His life or immediately after his death. The earliest written accounts didn't appear until 60 years after His death. And most current gospels weren't written until a couple of hundred years after His death.

So your professor bases his conclusion on inconclusive evidence. It can't be said for sure what anyone did immediately after the crucifixion or during Jesus' life.
