Not true. It was not Jewish custom to leave body hanging until the evening. And the next day was the Passover. It was against Jewish custom to leave the body up. And the Romans accepted Jewish custom and religion.
"“If a man commits a sin deserving the sentence of death and he has been put to death and you have hung him on a stake, 23 his dead body should not remain all night on the stake. Instead, you should be sure to bury him on that day, because the one hung up is something accursed of God, and you should not defile your land that Jehovah your God is giving you as an inheritance."-Deuteronomy 21:22, 23.
"Since it was the day of Preparation, so that the bodies would not remain on the torture stakes on the Sabbath (for that Sabbath day was a great one), the Jews asked Pilate to have the legs broken and the bodies taken away."-John 19:31.
As one reference work states:
the day of Preparation: The day preceding the weekly Sabbath. During this day, the Jews got ready for the Sabbath by preparing extra meals and by finishing any work that could not wait until after the Sabbath. In the case mentioned here, the day of Preparation fell on Nisan 14. (
Mr 15:42; see Glossary, “
Preparation.”) According to the Mosaic Law, dead
bodies “should not remain all night on the stake” but, rather, should be buried “on that day.”—
De 21:22, 23; compare
Jos 8:29; 10:26, 27.
to have the legs broken: In Latin, this practice was called
crurifragium. A brutal form of punishment, it was likely done in this case to hasten the death of those executed on stakes. A person hanging on a stake had difficulty breathing. With his legs broken, he would not be able to raise his body and relieve the pressure on his lungs, so he would suffocate.
