__TOC__ Sheelagh arrived at Sun Hill as a sergeant. Her time in Sun Hill was eventful, involving an affair with PC Des Taviner, which ended after his confession of murder, and the cot death of their baby, Niamh. Other problems that occured during her tenure at the station included her son, Connor, announcing his sexuality, which offended her religious beliefs and clashes with colleagues over potential racism. After being accused of racism and religious insensitivity following a high-profile court case in Episode 222 (17 June 2004) and following a number of other controversies, she chose to be demoted to the rank of Police Constable rather than become a Desk Sergeant at Hendon.
