The jury in the Peter Colwell shooting trial have been discharged after failing to reach verdicts on manslaughter charges against two gamekeepers.
On day eighteen of the trial at Caernarfon Crown Court, Mr Justice Picken stopped the jury's deliberations after more than 23 hours, having retired nearly a week ago.
Peter Colwell died when a shotgun went off in a 4x4 vehicle in a pub car park at the village of Llanbedrog.
Ben Fitzsimons, 23, of Nanhoron, Pwllheli, and Ben Wilson, 29, of Ely, Cambridge, denied manslaughter through gross negligence on the Boduan estate near Pwllheli.
Ben Fitzsimons' brother, Michael Fitzsimons, 25, also of Nanhoron, and Harry Butler, 23, of Llaniestyn, Pwllheli, were cleared of a single firearms count against them which they denied.
When he opened the prosecution case, QC Patrick Harrington said: ”The killing was neither deliberate nor malicious. But a young man died as the result of the cavalier disregard of the fundamental rules of gun safety by Ben Wilson and Ben Fitzsimons.”
The prosecution said a re-trial would be sought.
