A woman who shot a woman eight times then took a plea bargain and blamed her abusive husband has finally confessed to murder 14 years later.

Ashley Humphrey admitted to Piers Morgan on ITV's Killer Women that she came up with the plan to kill Sandra Rozzo and it wasn't her husband Timothy 'Tracey' Humphrey's idea, as she had testified in court in 2003.

Rozzo, Timothy Humphrey's ex-girlfriend, was due to appear in court to testify against him on battery and sexual assault charges, but before she had the chance, she was killed.

Ashley Humphrey waited for bartender Rozzo to finish work and followed her to her Pinellas Park, Florida, home where she shot the woman eight times at point-blank range.

'I suggested what if she were not to show up in court,' Ashley Humphrey, who was 20 at the time, said. 'That is where it started and it snowballed. I was the first to say it. I don't know why I let him into my head the way I did.'

Ashley Humphrey was sentenced to 25 years in prison for the execution and is due for release in 2028, while Timothy Humphrey is serving life in prison for the July 2003 crime.

At the time of the murder, instead of confessing to the crime, Ashley Humphrey took a plea deal that allowed her to testify against her husband.

Morgan said that the detective in the case said that if Ashley Humphrey admitted it was her idea at the time, she could have received the death penalty.

He told The Mirror: 'Until that point, I was quite sympathetic to her claim that she had acted entirely under the manipulative influence of her nasty piece of work husband.

'But Ashley's admission that the murder was HER idea changed everything. At that point, I realised I was dealing with a very dangerous, disturbed woman.'

The woman told Morgan that she deserved a life sentence, but insisted that Timothy Humphrey should remain behind bars as well, because if he was released he would still be a 'violent manipulator'.

'There is no hatred or violence in me,' she told Morgan. 'I certainly didn't save myself with a 25 year sentence.'

Ashley Humphrey is currently incarcerated at the Gadsden Correctional Facility in Quincy, Florida.

Timothy Humphrey is serving his life sentence at the Everglades Correctional Institution in Miami, Florida.

ITV's Killer Women will air on Thursday at 9pm.
