BY Rachelle Blidner NEW YORK DAILY NEWS Saturday, January 31, 2015, 12:14 PM Melinda Lynn Muniz, 25, has been arrested and charged with capital murder after she allegedly suffocated to death her fiancé's 2-year-old daughter Grace Lillian Ford. Muniz staged a break-in to cover up her crime. A Texas woman accused of killing her fiancé's 2-year-old daughter in a staged home invasion was dumped by her beau over racy photos and videos she sent her personal trainer just hours before the slaying, police said. Melinda Lynn Muniz, 25, was charged with murder after she was caught on surveillance footage buying supplies needed to kill Grace Lillian Ford, 2, — with the tiny girl in tow — right before the assault in Plano Jan. 9, police said. The night before, Grace's father discovered scantily-clad pictures and videos on Muniz's phone, fiancé Mitch Ford told police. She sent them to her personal trained named Mike, who she had been texting for about a month — around the same time she and Ford had been engaged — Ford said. The next morning, Ford confronted Muniz over a video he found of her dancing topless. He broke up with her, telling her to move out of the Eastside Villages Apartment complex, Ford said. He told her to sell her engagement ring to buy a car since he was taking his Mercedes Benz in the split. Ford left for work and put Grace in Muniz's care, as he did every work day, he told police.
