Susan Ellsworth still remembers the phone call she recieved from her daughter telling her that her grandson was dead."My legs gave out. I just fell on the ground," Ellsworth said. Tyrese Parson, 17, was found dead on a sidewalk on the east side of Des Moines on June 8, 2018. His case is still unsolved. "It makes me mad. I just think you took him away from us. You didn't have any right to do that. Whoever you are," Ellsworth said.
