Rosemary Duenez says her heart breaks all over again when she wakes up in the morning and remembers that her son – 34-year-old Ernest Duenez Jr. – is gone. And she’s going to do everything within her power to make life miserable for the man that she’s holding personally responsible for his death. On Thursday afternoon, Duenez took up a position just outside of the Manteca Police Department car park armed with flyers, massive cardboard signs and traditional pickets to raise awareness of the fatal police shooting of her son on June 8.
