Keith Turner, 60, from Northumberland, was released on licence in 1993 after serving 20 years in jail for the manslaughter of his mother and sister at their home in Cramlington.
He got a job working for a charity in Slough in 1998, but two years later was arrested on suspicion of issuing himself four cheques worth a total of £10,000. He failed to appear in court to face charges.
Criminals thinking of fleeing to Spain's Costa Del Crime are being warned that Spain is "not a safe haven." The warning comes as British and Spanish authorities issue a joint list of the UK's most wanted criminals thought to be on the run in Spain. Hank Cole from the NCA said:
Spain is not a safe haven. Fifty three fugitives have been caught since Captura was launched, and many more linked to other operations.
The most important thing though is the power of this campaign to harness the eyes and ears of the public, both here and in Spain.
