Glynn was a plainclothes Detective Constable with the Weatherfield Police force. On 22nd February 2010, Glynn and DS Carr were assigned to an investigation into the death of Joe McIntyre whose body had recently been found in Lake Windermere. Glynn and Carr broke the news about Joe's death to his widow Gail and began questioning her about Joe's activities. Although Gail initially stated that Joe had been working in Cumbria, she soon changed her statement and admitted that she had had an argument with Joe when he told her about his plan to fake his own death, and that Joe had sailed away in his boat when Gail was unable to stop him going ahead with his plan.
