Robbie grew up in Harlem, and as a teenager was a classmate of Lonnie Thompson Lincoln, later infamous as the brutal hit man Tombstone. Robbie once wrote an article for the high school newspaper about Lincoln's bullying and extortion, but spiked it after being threatened by Lincoln. Years later, while working as a reporter in Philadelphia, Robbie witnessed Lincoln murder one of Robbie's contacts. Once again, Lincoln threatened Robertson, and the journalist fled to New York City and began working for the "Bugle". He told no one of the murder he witnessed.
