There are several stories regarding McCoy, some which seem a little far fetched. He is believed to be the person that the expression “The Real McCoy” refers to. In one of his crazier stories he apparently accepted an unsanctioned fight against a man that weighed nearly 100 lbs more to earn extra money. When the fight started his corner men threw tacks on the floor and his bare footed opponent stepped on them, at which point McCoy was able to knock him out.

McCoy’s boxing career ended in 1914 and afterwards he had some success in Hollywood. In 1924 he killed his girlfriend, Teresa Mors. After shooting her in the head he held 12 people hostage the following morning at Mrs. Mors antique shop. He was eventually convicted of manslaughter and sent to San Quentin prison. He was released on parole in 1932, and in 1940 committed suicide by overdosing on sleeping pills.
