Allan Grimson

Allan Grimson (born 1958) is a convicted British murderer who is responsible for murdering at least two men and is suspected of killing others, possibly up to another 20 undiscovered victims. The judge, who sentenced him to a minimum term of 22 years at his trial, said that Grimson was a serial killer by name, but not by number. Because his two victims were killed on the same date just a year apart (12 December), detectives believe there may be more victims out there as yet unidentified.
