After Diana murders Mike, she keeps the bloody murder weapon, Jerry's brass putter. Professional golfer are only allowed to carry14 clubs, and would never ever carry 2 identical putters, yet Jerry has no issue using his putter the next morning.
Sudden death playoffs are never played the next day. They are only ever played immediately following the regulation 18 holes. (They would never make everybody come back the next day for what could be one hole and ten minutes at best.) Before television it was not uncommon to schedule a full 18 holes playoff for those tied for first, however now it is either sudden death or the aggregate score after 3 selected holes and sudden death after that should the players still be tied, both immediately following the regulation 18.
When Diana is dubbing the "spy" footage of her and Jerry in bed, the camera is obviously moving.
The police note that the only person in the professional building that Jerry might have gone to is a psychiatrist, the only other choice being a finance company There are 2 Dentist and 5 other MDs listed on the Medical Arts Building Directory, however no finance company is listed.
