Dana Hill was 25 when he was shot in the head at a Revere Beach bar on September 20, 1981, and died three days later. The shooting followed an earlier stabbing of James Rich by four men believed to be Hells Angels; Rich’s friends Robert L. Cobb, Arthur A. Corbett, and Andrew J. Millyan set out to retaliate and targeted any Hells Angels they encountered.

At the bar Dana Hill, who was not a member of any motorcycle gang but had the appearance of a biker, was mistaken for a Hells Angel. Andrew J. Millyan fired a shotgun, fatally wounding Hill. Cobb, Corbett, and Millyan discarded the weapon but were arrested after a police investigation and indicted for first-degree murder on a theory of joint enterprise.

On May 19, 1982, Arthur A. Corbett and Andrew J. Millyan were convicted of murder in the first degree and Robert L. Cobb was convicted of murder in the second degree; all three received life sentences.
