Michael Stone Stone's attack killed three people - civilians Thomas McErlean (20) and John Murray (26), and 30-year-old IRA man Kevin Brady. After his arrest, he admitted to three other murders, including killing Catholic milkman Patrick Brady (36) in south Belfast in 1984. He also admitted the killings of joiner Kevin McPolin in Lisburn in 1985 and bread delivery driver Dermot Hackett near Drumquin in Co Tyrone two years later. Stone was released in 2000 under the terms of the Good Friday Agreement. However, he was sent back to jail in 2006 after an attempt to murder Sinn Fein leaders Gerry Adams and Martin McGuinness at Stormont.
