Leon Southam was a drug dealer who lived on Claybourne Estate in 2011. Leon served a prison sentence some time prior to August 2011 but was released on parole. His girlfriend, Ruth Walsh, and their child remained incarcerated in the mother and baby unit of Norcross Prison. Leon took drugs to the prison when visiting Ruth and they used the baby to smuggle them, in order to sell them to inmates. One of the inmates, Fiz Stape, grassed Ruth up and she was evicted after her cell was trashed by prison staff looking for the drugs.
