He just turned seven. There was no reason for her to take his life she wasn't supposed to have him. She could have just gave him back to us," said Pinckney.She says she knows they weren't social distancing but the grief was just too much to try to bear his sudden loss alone."It looked like he was being abused over the last couple months. My brother kept trying to go down and get custody back and trying to do what he needed to do to get him," said Pinckney.
