The gunman who shot dead a reporter and a cameraman sent a scathing letter to a pawn shop for allegedly not saying thank you, it has emerged.

Owner Doug Grant told INSIDE EDITION:“I talked to the clerk at the time and there was nothing memorable about it whatsoever."
But then Flanagan sent a nine-page letter telling staff that they should always say “thank you” to customers for buying items and should never say “have a nice day” because it lacks sincerity.
He also wrote: “Is this a rant? Ya betcha it is. At this point are you bored? Are you defensive? Do you think I am just a crazy lunatic? If not, keep reading. I am not finished yet.”
