The man accused of killing Elle Edwards suggested his co-defendant contradicted his account of where he was on the night of the murder "to get a lenient sentence".
Connor Chapman is on trial at Liverpool Crown Court accused of firing 12 shots at a group in front of the Lighthouse Pub, Wallasey Village, shortly before midnight on Christmas Eve last year.
"Wholly innocent" Elle, 26, was struck twice in the head by bullets from a Skorpion sub-machine gun. Five men, including alleged "intended targets" Kieron Salkeld and Jake Duffy, were also injured.
