Detective Sherlock entered a restaurant, he heard a voice coming from the kitchen of the restaurant “No Andrew, Don’t shoot“.
Just after that, he heard a falling down of a person. Sherlock rushed into the kitchen where he found women lying dead on the floor and there were three persons. All three persons were very close to the dead body and the gun was in close proximity of all of them.
These three persons were “An Actor” , “A Doctor” and “A Pilot”.

Sherlock shoots the pilot. Why ?
