Manchester Pusher
The Manchester Pusher is the name given to a hypothetical serial killer, or individual, alleged to be responsible for the deaths of a number of people whose bodies have been retrieved from the waterways (principally the canals) of Greater Manchester, England, since at least 2007. Proponents of the theory claim that the "alarming" number of deaths that have occurred in the Rochdale, Ashton and Bridgewater Canals since the early 2000s cannot all have occurred as the result of accidents or suicides, and must have involved some element of foul play.
