The girlfriend of a hitman who killed a mother of five as she tended her horses in a New Forest field was freed from jail today. Lian Doyle agreed to hide the trainers worn by Justin Robertson when he murdered Pennie Davis because he had been paid £1,500 by the son of the victim's ex-lover. She was today sentenced to 10 months in prison, but was released immediately because she has already spent six months on remand. Killing: Lian Doyle, left, helped to cover up the murder of Pennie Davis, right, in September last year . Doyle, 24, pleaded guilty to perverting the course of justice after she admitted disposing of her boyfriend's shoes, thinking he had worn them to commit a burglary. Robertson was jailed for life yesterday after being convicted of murder, while Benjamin Carr also received a life sentence for paying the killer to murder Mrs Davis, 47. Winchester Crown Court heard that Carr wanted the victim dead because she was planning to tell police that he had sexually assaulted someone. Today the court was told that Robertson convinced Doyle to hide his trainers, making her think that he had carried out a burglary while wearing them. She lied to police on his behalf - but when she realised that the trainers were evidence in a murder inquiry, she confessed to what she had done. Boyfriend: Doyle was manipulated by Justin Robertson, left, who was paid to kill Mrs Davis by Benjamin Carr, right . Victim: Mrs Davis was found dead in a paddock in the New Forest in September 2014 . Mr Justice Popplewell told Doyle, from Hythe in Hampshire: 'On September 2 last year, after Pennie Davis had been killed, Justin Robertson had given the trainers he had been wearing that afternoon to a neighbour to put them in the rubbish. 'Two days later he asked you to retrieve them and burn them but rather than burning them you gave them to somebody else to dispose of. 'You didn't know they had been worn to commit a murder and you thought Justin Robertson had been wearing them for a burglary.' He added that following her initial arrest, Doyle was interviewed but failed to inform police about dumping the trainers, which 'impeded' their investigation. The judge said: 'I'm satisfied that Justin Robertson was a dominant character and he is likely to have manipulated you.' Couple: The victim's body was discovered by her new husband Peter, pictured . Family: Mrs Davis' relatives are pictured outside Winchester Crown Court yesterday . Doyle's lawyer Charlie Gabb said in mitigation that she was reliant on Robertson, and would stay with him in friends' houses because she did not have a home of her own. 'She must have been somewhat in awe of him in light of her own vulnerability,' he said. 'For a young lady who has never had any experience of the criminal justice system it's been a considerable shock. 'There is a stark reality that she is on her own and Mr Robertson can no longer provide for her.' Mrs Davis was found dead in a paddock near Beaulieu, Hampshire in September last year by her husband Peter, whom she had married just months earlier. Robertson, 36, was paid £1,500 in counterfeit banknotes to kill her by Carr, 22, who had a longstanding grudge against her dating to her long relationship with his father. The court heard he wanted her dead because he feared she would report sexual assault allegations against him to the police. The plot unravelled when Robertson dropped the keys to his getaway car near to the murder scene, allowing officers to track him down.
