People generally kill for love, jealousy, financial or sexual gain. Not Peter Wade, a 23-year-old labourer. He killed 70-year-old Dublin gardener Patrick Quinn simply because he didnt like the derogatory way Quinn spoke about a mutual friend.
Wade persuaded another friend to knock on Quinns door, determined, as he put it, to teach the old man a lesson, and when Quinn came to the door he dragged him into the street and kicked him to death. He was hanged on Tuesday, January 15th, 1884, at Dublins Kilmainham Prison.
