My conspiracy theory

Here's my uneducated, conspiracy theory of what happened to these two and the dog.

This is based on the information that both were found deceased on the floor, with pills and open bottles around the wife's body and the dog having been found dead also.

1) I believe that 95 year old Gene Hackman fell (like anyone over the age of 60 is vulnerable of doing) and died.

2) His wife (in her 60s) finds Gene dead. She has two choices. Call the coroner (he's already dead, and she knows it) or join her beloved Gene Hackman. How does she join her beloved gene? She swallowed a bunch of pills, leading to her collapse and death. If she collapsed suddenly by a counter, this would also explain the space heater having fallen off the counter next to her.

3) The one dog left inside the house eats the leftover pills on the ground, probably due to hunger as I'm assuming that the Hackmans didn't put WEEKS WORTH OF FOOD out for the dog on a daily basis, just incase this happens. No, they probably filled the bowl just enough to get the dogs through until that night or the next morning. You know, LIKE ALL DOG OWNERS.... and now the dog is dead also.

Is this at all highly unlikely?

Ask your aging grandparents what would they do if one of them suddenly dies. The answer might shock you!!
