Sheridan had been in and out of crime for most of his adult life. A life-long Londoner, he’d done various gardening jobs over the years but nothing permanent, and no thought of a career. With little to live on, the temptation of crime was always there to earn some extra money. He got involved in a gang that dealt drugs. It soon got serious. As a result of his criminal activity, Sheridan was shot at three times, the last time with a gun held to his head, point blank.
