Obviously when being told Sheila was murdered, it would be normal to be in shock & disbelief. He had voluntered a lot of information to the police suggesting Sheila had committed murder/suicide. .
He may ask -
Who said this?
Can I speak to the expert?
Are there any suspects?
Was it a burglary gone wrong?
How could a burglary end up in a massacre?
Has been more than one expert opinion?
Do the police believe it was one or more murderer.
Who else was Nevill referring to when phoning him?
How can I help?

Instead Bamber just shrugged his shoulders & suggested Crispy, nerves or a woman (she) fired the second shot.
