The family of a grandmother who has been missing for almost three months has issued a heartbreaking plea to the public. Rita-Marie Collin was last seen walking along Woy Woy Rd in Kariong, on the NSW Central Coast, about 10.45am on May 5. “We wake up each day wanting answers, wanting to know where she is, and wanting to bring her home,” she said. There has been no sign of her since May 5 despite numerous searches near her last known location on Woy Woy Rd in Kariong. “Multiple coordinated searches have been conducted across bushland in Kariong and along Woy Woy Road, but without new information, the investigation cannot move forward.”
