Giggling. Jeremiah lived hundreds of years before the time of Jesus, and so could not possibly have been crucified with Him. Paul lived at the time of Jesus, but we know that he lives for many decades after Jesus’ death helping spread the message of Christianity and writing much of the New Testament. He also could not possibly have been crucified alongside Christ and survived to do all this.
Carefully read the Gospel accounts of the Crucifixion - two thieves were crucified alongside Jesus, neither is named. We know that both died on the same day as Jesus. Nowhere in scripture is either Paul or Jeremiah ever accused of being a thief, let alone shown as being crucified for it.
Conclusion: whatever you think you might have been told, there is simply no possibility that Jeremiah was crucified. As you know, St Peter was, so was St Andrew. All the stories of St Paul’s death indicate that he was killed by the sword.
There is absolutely no possibility that Jeremiah or any other OT prophet was crucified either. As has been pointed out, crucifixion was invented and exclusively used by the Romans. They had not taken over Israel/Judea or any other area where the OT prophets lives and taught in OT times. So it is impossible.
