What John was at the crucifixion of Jesus?

Historically, it would have been possible for John the Baptist to be at the crucifixion, since Josephus tells us that John was not imprisoned and executed until 35 or 36 CE, long after the accepted time of Jesus crucifixion. However, The Bible makes no mention of John the Baptist being present, and even tells us that John was executed quite early in the mission of Jesus.

So, from a historical perspective it would have been possible, but unlikely, for John the Baptist to be at the crucifixion. From a gospel perspective, John could not have been there because he himself was already dead.
