We were asleep

Matthew 28:11-15 - While the women were on their way, some of the guards went into the city and reported to the chief priests everything that had happened. When the chief priests had met with the elders and devised a plan, they gave the soldiers a large sum of money, telling them, "You are to say, 'His disciples came during the night and stole him away while we were asleep.' If this report gets to the governor, we will satisfy him and keep you out of trouble." So the soldiers took the money and did as they were instructed. And this story has been widely circulated among the Jews to this very day.

I wonder who "leaked the story to the press," so to speak. I can think of only 3 possibilities.

• One of the chief priests and elders couldn't keep his mouth shut.
• One of the soldiers couldn't keep his mouth shut.
• Someone overheard the plot and couldn't keep his mouth shut.

My money is on the soldiers.

I wonder if they kept quiet about how much money they got. I wonder how long they kept it.
