When they realised they had committed Deicide.

[Matthew 27: 45-54] ~ Now from the sixth hour there was darkness over the whole earth until the ninth hour. And about the ninth hour Jesus cried with a loud voice, saying: Eli, Eli, lamma sabacthani? that is, My God, my God, why hast thou forsaken me? And some that stood there and heard, said: This man calleth Elias. And immediately one of them running took a sponge and filled it with vinegar and put it on a reed and gave him to drink. And the others said: Let be, let us see whether Elias will come to deliver him. And Jesus again crying with a loud voice yielded up the spirit. And behold the veil of the temple was rent in two from the top even to the bottom, and the earth quaked and the rocks were rent. And the graves were opened. And many bodies of the saints that had slept arose †; and coming out of the tombs after his resurrection came into the holy city and appeared to many. Now the centurion and they that were with him watching Jesus, having seen the earthquake and the things that were done, were sore afraid, saying: Indeed this was the Son of God.

[John 19: 36] ~ For these things were done that the scripture might be fulfilled: You shall not break a bone of him.

[Psalms 33: 21] ~ The Lord keepeth all their bones, not one of them shall be broken.
