Bates was born into an
Ulster Protestant family and grew up in the
Shankill Road area of
Belfast. He had a criminal record dating back to 1966, and later became a member of the
Ulster loyalist paramilitary organisation, the
Ulster Volunteer Force (UVF). Bates, employed as a barman at the Long Bar, was recruited into the Shankill Butchers gang in 1975 by its notorious ringleader,
Lenny Murphy. The gang used The Brown Bear pub, a Shankill Road drinking haunt frequented by the UVF, as its headquarters. Bates, a "sergeant" in the gang's hierarchy, was an avid participant in the brutal torture and savage killings perpetrated against innocent Catholics after they were abducted from nationalist streets and driven away in a black taxi owned by fellow Shankill Butcher,
William Moore. The killings typically involved grisly-throat slashings preceded by lengthy beatings and torture. Bates was said to have been personally responsible for beating James Moorhead, a member of the
Ulster Defence Association, to death on 30 January 1977 and to have played a central role in the kidnapping and murder of Catholic Joseph Morrisey three days later. He also killed Thomas Quinn, a derelict, on 8 February 1976 and the following day was involved in shooting dead Archibald Hanna and Raymond Carlisle, two Protestant workmen that Bates and Murphy mistook for Catholics. Lenny Murphy was in police custody at the time the shooting attack against the Chlorane Bar took place. Bates was arrested in 1977, along with Moore and other "Shankill Butcher" accomplices. His arrest followed a sustained attack by Moore and Sam McAllister on Catholic Gerard McLaverty, after which they dumped his body, presuming him dead. However McLaverty survived and identified Moore and McAllister to the
Royal Ulster Constabulary who drove him up and down the Shankill Road during a loyalist parade until he saw his attackers. During questioning both men implicated Bates, and other gang members, leading to their arrests. Following a long period spent on remand, he was convicted in February 1979 of murder related to the Shankill Butcher killings and given ten life sentences, with a recommendation by the trial judge,
Mr Justice O'Donnell, that he should never be released. ==In prison==
