The gunman behind the "public execution" of a dad-of-two was previously said to be at the centre of a separate deadly feud.
Rueben Murphy shot Patrick Boyle twice in the chest in a Huyton cul-de-sac last summer. The masked assassin used an electric bike to carry out the killing with the help of his best friend Ben Doyle.
Self-confessed drug dealer Murphy, 26, claimed he was "off me head on ket" at the time of the shooting in a back garden near Doyle's house. He denied knowing or shooting the 26-year-old victim, while Doyle, 24, claimed the shooter was a man he refused to name, because he wasn't a "snitch".
