Two teenagers are facing charges for allegedly trying to strangle and poison a grandmother. The 80-year-old victim was reportedly riding in a car with her granddaughter and her boyfriend when the boyfriend put a rope around her neck. The victim was able to break free, and the teens were later found and arrested by Oklahoma City officers. One suspect's brother told KWTV the teens were upset the victim would not let them spend more time together, and previously attempted to poison her.
