What happens to Tom Robinson? Be specific.

Tom Robinson is shot and killed in the midst of trying to escape prison.

“They shot him,” said Atticus. “He was running. It was during their exercise period. They said he just broke into a blind raving charge at the fence and started climbing over. Right in front of them—”
“Didn’t they try to stop him? Didn’t they give him any warning?” Aunt Alexandra’s voice shook.
“Oh yes, the guards called to him to stop. They fired a few shots in the air, then to kill. They got him just as he went over the fence. They said if he’d had two good arms he’d have made it, he was moving that fast. Seventeen bullet holes in him. They didn’t have to shoot him that much. Cal, I want you to come out with me and help me tell Helen.”
