I am sure there is a LOT more to the story than what is printed. The 2 things that stand out is the coroner ruled the death as a homicide
article says he died April 12, but she was only charged August 14? did they recently exhume the body to investigate cause of death or did it actually take 4 months for them to conclude homicide? this sounds very odd.
I really doubt that woman had the strength to bludgeon anyone to death, let alone with something as lightweight as a coffe cup. Or someone else was involved.
