Gary Price says his mother, Marion, went from being a "bubbly" person to a "shell of a woman" during her abusive and controlling marriage.
"He [her ex-husband] would control what she spent her money on," Gary says. "He gradually ground her down and tried to encourage her to leave work so eventually it would just be her and him and she wouldn't be able to leave."
After the relationship ended, Marion's family came to realise how controlling her ex-husband, Michael Reader, had been.
"We found out he was using a tracking device," Gary says. "She was dropping some shopping off for her mum and he was waiting at the top of the street."
In 2019, Marion was followed to her home by her estranged husband, who then shot her dead while she was still in the car. "As she pulled into her drive he pulled up alongside her and shot her through the window," Gary says. "She hadn't even taken her seatbelt off."
Reader was found guilty of her murder and is serving a life sentence.
