Asked by his barrister Kier Monteith QC why 16 days later he had stabbed and strangled Miss Nash, Jessop replied: “Because of that medication.”
Jessop claimed that Miss Nash had threatened to shoot him on an earlier occasion, with a gun he alleged she was holding for drug dealers, and that while they were in the toilet, he feared that if he didn’t kill her, she would kill him.
On Tuesday, Mr Cotter delivered his closing speech on behalf of the prosecution.
He told jurors that evidence given on the stand about Clare's lifestyle had been "quite literally a character assassination" by Jessop, who he accused of "spitting on her grave".
