Detective Rockford was jogging near the beach at 4:30 am.
He hears a sound near the shack "No Michael, Please Do not shoot me".
Next instance he heard the sound of gunfire. Rockford rushes to the shack where he finds women lying dead and a gun in close proximity of three "Doctore Lawyer and a Teacher".
Rockford immediately knew that the Lawyer has committed the crime. How?

It lies behind stars and under hills, And empty holes it fills.
It comes first and follows after, Ends life, and kills laughter.
