1.45. A man is found dead outside a large building with
a hole in him. (JM, modified from PRO)

1.45 answer: The man was struck by an object thrown from the roof of the
Empire State Building. Originally I had the object being a penny, but
several people suggested that a penny probably wouldn’t be enough to
penetrate someone’s skull. Something aerodynamic and heavier, like a dart,
was suggested, but I don’t know how much mass would be required.

1.45a. Variant: A man is found dead outside a large marble building with
three holes in him.

1.45a answer: The man was a paleontologist working with the
Archaeological Research Institute. He was reviving a triceratops frozen in
the ice age when it came to life and killed him. This couldn’t possibly
happen because (among other reasons) there were no triceratops during the
ice age. (from Peter R. Olpe)
