The other thing thats suspicious in this case is that Ronda was found in the closet covered with a blanket and it looked like she was lying down
when she supposedly pulled the trigger, another highly unusual position or state when people do commit suicide.
By this we are to assume that she got up to retrieve the revolver out of the draw, find bullets and insert them
because the gun was unloaded, go back into the closet, close the door and lie down, pull a blanket over herself then pull the trigger.
Thats just too weird. Also she had spoken to her mother and got prepared to leave the next day. Meaning there was a predetermined initiative to
carry on in spite of her personal problems with Ron.
