Had been dead for some time. Found in different rooms. Wife found near space heater with open bottle of pills spilled on counter. Carbon monoxide not ruled in or out yet. So, scenarios:
1) all died from CO poisoning. Wife just happened to be trying to take meds because she felt ill. Don’t know what meds were yet 2) Gene and or dog died from CO poisoning and wife took pills out of grief 3) No CO. Finds Gene dead of being 95. Kills self and dog. 4) Mutual suicide and killed dog or died of no food or water depending on how long they had been dead.
