A Scottish university lecturer faces 50 years in a U.S. jail for trying to murder her husband after finding his child porn.Joanna Findlay, 41, blasted Gary Trogdon in the chest at their home in Hollywood, Maryland, but failed to kill him.Mr Trogdon, a 55-year-old former U.S. Air Force lieutenant colonel, then took the gun and killed himself.Jurors at St Mary's County Circuit Court found Findlay, originally from Blairgowrie, Perthshire, guilty of attempted second degree murder following a two-and-a-half-day trial.Findlay was also found guilty of the statutory firearms offence of using a handgun in the commission of a felony.State attorney Richard Fritz said Findlay now faces a potential 30 years in jail for attempted second degree murder, and potentially another 20 years on top for the firearms offence.Mr Fritz said: 'The jury found that she tried to murder him before he shot himself. They decided there was not enough evidence as to whether he committed suicide or she murdered him.'The jury maybe thought that he committed suicide, but found that she had tried to murder him as well.Findlay, who was an English lecturer at Maryland University, insisted throughout that Mr Trogdon had in fact shot himself over the embarrassment at his child porn cache.The trial heard that Mr Trogdon had gone to a local support group the morning before he died, after his wife insisted he seek help for his obsession with child pornography.Later that day, on October 30 last year, the couple were seen in good spirits and had gone to a Mexican restaurant in California, Maryland, for dinner with a neighbour after helping work on their chicken coop.However the court heard there was a rapid deterioration in their behaviour and later that night Findlay tried to overdose on drugs but her husband took them off her.She claimed in court that he later assaulted her after she again brought up the child pornography.She said: 'He pushed me down on the bed and he laid on top of me... He wouldn't let me up.'After more struggling, Findlay said she eventually freed herself and took a .22-calibre pistol from a coffee table drawer in the living room.She said she shot the gun into the floor to scare him away and then called police.
