Landlady Caroline Evans was five months pregnant

Magistrates in Ammanford, Carmarthenshire, west Wales, fined John Bruce, of Danyrallt Lodge, Llangadog, �500 with costs and confiscated the gun, after deciding he had failed to keep the firearm secure.

He had left the single barrelled gun out of its cabinet in his bedroom. He said he left it unattended at home for just three hours. The keys to his front door were in an unlocked porch.

Bruce denied failing to comply with a shotgun certificate by not keeping the firearm properly secure.

The court heard on Monday how Bruce's friend William Davies took the gun and used it to kill Llangadog pub landlady Caroline Evans in February. Mr Davies then turned the gun on himself.

The bodies of 59-year-old Mr Davies and 27-year-old Ms Evans - who was five months pregnant - were found inside the Red Lion pub, which Ms Evans ran with her father.

It later emerged that Mr Davies had previously been convicted of threatening her with a shotgun.

Officers said at the time that Mr Davies did not have a gun licence and that the gun he had at the time of the previous court hearing had not belonged to him.

William Davies took the gun from his friend's house

He received a two-year rehabilitation order after admitting slapping and threatening to shoot Ms Evans.

At the time, Mr Davies was said to be severely depressed but was not detained after psychiatrists ruled he was "no danger to anyone else".

The Crown Prosecution Service dropped a charge of threatening to kill in favour of lesser charges, which carried a community-based punishment sentence rather than imprisonment.

Following the double shooting, there were renewed calls for an inquiry into the CPS decision.

In March it was revealed that two independent reviews would examine the way agencies dealt with events leading up to the tragedy.
