Cause of death is sometimes ambiguous because some things are unknown. Perper did his job...and if he was duped by KE, he's got a fall guy...insufficient information.
Wonder what KE forgot to tell him? Wonder WHEN she made her plane reservations to "GET OUT OF TOWN" because it was supposedly a last minute "necessity" to get to Ca? If she left the evening BEFORE Anna died, all she did was sleep and call in the morning....when Anna was okay. Baloney...Bet she was instructing Howard on "HOW TO". dON'T FORGET TO CONSIDER THE 3 HOUR TIME DIFFERENCE.
