In Quebec, there is the case of William Fyfe, a serial killer who admitted to eight or nine murders. The first time he was arrested it was on the basis of a fingerprint found on a door frame.
However, all other evidence that arose afterwards to convict him was DNA evidence. For instance, there was DNA found inside of a ring which belonged to a woman he had killed, which had been brought to his mother's house in Barrie, Ontario. Police officers had managed to get ahold of this ring and identify the victim.
That said, at first he was arrested on the basis of his fingerprints on a door frame. Afterwards, DNA allowed for links to be made to the other murders which followed.
