The brother-in-law of an underworld "Mr Big" was involved in his assassination, Liverpool crown court has heard.
Paul Massey, 55, was shot dead outside his Salford home, allegedly by Mark Fellows, 38, with the help of co-accused Steven Boyle, 35.
Massey's partner Louise Lydiate is the sister of Stephen Lydiate, who was interviewed as a "person of interest" after the murder in July 2015.
Police were told Mr Lydiate, who is not on trial, was involved, the jury heard.
Mr Lydiate, described as "violent man", was also battered and attacked with acid at the funeral of Mr Massey, the court heard.
Mr Lydiate has never been charged with any offence connected to the murder.
One of those involved in the attack on Mr Lydiate - and a pall bearer at the funeral - was notorious mob fixer John Kinsella, 53, from Liverpool, the jury was told.
Mr Fellows and Mr Boyle are alleged to have murdered Mr Kinsella three years after the murder of Mr Massey.
They both deny the charges.
