another very violent episode of the S.W.A.T tv series

There was a episode of the old S.W.A.T tv series, from during its first season shown on abc-tv, i forgot the name of the episode of, it was a psychopathic satanist ,who was a leader of a very violent coven of killers called the Butcher Brigade who breaks out of a hospital, with the help of his fellow coven, who a police officer and maybe a doctor.
this psychopthic satanist goes out looking for the people who sent him to prison, i think was able to kill most of the prosecutors who helped send him to prision.
this same very violent psychopathic satanist was later killed in a very violent gun battle, Los Angeless POLICE S.W.A.T LT. Hondo Harrelson, along with his very Brave S.W.A.T members, some or most of the members of that violent coven of killers gave up to the police in this episode of the S.W.A.T tv series.
