I was thinking about Prescription Murder, and how they used the chalk / tape body outline around Mrs. Fleming. (And funny though, she wasn't even dead!) I don't remember this technique used very often for other murders, was it? Also, what about other instances where the initial murder failed, resulting in the victim being hospitalized. I can think of at least two.
I just watched Now you see him and noticed they taped around the body outline.
I just watched BYE BYE SKY HIGH IQ MURDER CASE, and they also taped off the outline of the body upstairs.
