Sister McKinley was one of the medical staff who took care of Albert Tatlock when he was hospitalised in March 1973. Albert had been gassed by a newly installed cooker at 1 Coronation Street. The cooker had been installed by Jerry Booth, but it hadn't been sealed properly. Throughout Albert's treatment, Sister McKinley kept Ken Barlow appraised of his relation's condition, emphasising the danger of complications due to his age and possible hyperstatic pneumonia. After a week in hospital, Albert was put on the danger list but he managed to pull through and make a full recovery.
