The Reeces dairy was in Greenwood Lane it backed onto Manor Road School, there where 2 sisters murdered in Greenwood Lane in 1973, but I don't know if they had anything to do with the Dairy :-
On 5th May, two sisters, one aged 63 the other 54, were murdered in Greenwood Lane. They had received horrific injuries to the head and neck as well as stab wounds. One woman was nailed to the floor with a 6 inch nail through her breast. The ambulance was called when the men found the sisters in pools of blood. A neighbour said she had noticed that one of the sisters had became withdrawn and interested in Spiritualism. The tragedy happened on the birthday of one of the ladies. Two youths, Anthony Atherton (also known as Mark Anthony Stanhope) and Terence McGee, who had been kind to them when there was trouble with vandals on bonfire night had taken lodgings with them. The young men, aged 19 and 22, were apprehended by the Police and later charged with the murders. They were tried in the Liverpool Crown Court where they pleaded guilty to manslaughter on the grounds of diminished responsibility but not of murder. They were jailed for life.
