There is nothing new in stalking. Mary Gallagher was stalked by her estranged husband Thomas for many weeks during the summer of 1860. Gallagher knew Mary called frequently at a factory where friends worked, and on June 8th he followed her into the building.
Before anyone could ask him what he was doing there, he grabbed Mary by the waist and began stabbing her in the neck and face. Someone intervened, and Mary, screaming with pain, was taken to hospital, where she died two months later.
Gallagher was convicted of her murder and hanged on Saturday, September 8th, 1860, at Kirkdale Prison.
