CHICAGO  - An Ohio woman and her son appear to have conspired to kill the woman’s grandchildren, their pets and themselves with carbon monoxide as a result of a custody dispute, reports said. Police believe grandmother Sandy Ford, 56, and uncle Andy Ford, 32, were trying to keep the kids’ parents from gaining custody of Paige Hayes, 10, Logan Hayes, 7, and Madalyn Hayes, 5. The bodies were discovered after Randy Ford, 60, came home from work and found notes from his wife, son and grandchildren.
