On 22 January 1976, a second UDR soldier, Sergeant James Roderick Shane McDowell (aged 29, an optical worker, also from Lurgan) was arrested and charged with the Miami killings. He served in C Company, 11th Battalion UDR. The RUC were led to him through his glasses which had been found at the murder scene. Tests done on the glasses, which were eventually traced back to McDowell, revealed that the lenses were of a prescription worn by just 1 in 500,000 of the population.
