Funny that a simple heart attack could cause so many injuries and broken bones.
She had major broken bones. IMO, she was bopped from behind, HINO waited before he called Bobby Schindler who also lived in the complex. IMO, HINO was hoping she'd die but oops, she didn't die after the whack to the head from behind. So, HINO got connected to people who would help him finish the job. He was a dedicated sociopath and it almost goes without saying that money is the root of all evil.
