Who did Peter say the men of Israel had killed?

Both answers are correct

Acts 3:12-15 (12) When Peter saw this, he said to them: Men of Israel, why does this surprise you? Why do you stare at us as if by our own power or godliness we had made this man walk? (13) The God of Abraham, Isaac and Jacob, the God of our fathers, has glorified his servant Jesus. You handed him over to be killed, and you disowned him before Pilate, though he had decided to let him go. (14) You disowned the Holy and Righteous One and asked that a murderer be released to you. (15) You killed the author of life, but God raised him from the dead. We are witnesses of this. NIV
