       Duffy and Mulcahy are thought to have attacked at least 19 women in the 1980s Credit: PA:Press Association What happened to John Francis Duffy and David Mulcahy?

       Duffy was put on trial in February 1988 and was convicted of two murders and four rapes, though he was acquitted of raping and killing Anne Locke.

       He was given a minimum sentence of 30 years by the judge.

       Cops suspected Mulcahy had been involved for a number of years but didn’t have the evidence to charge him.

       It was only after Duffy implicated him 15 years after he had been convicted could they act.

       Mulcahy, a married father of four, had been tracked for several months by police prior to his arrest.

       DNA tests which were not used in the original trial but were now available managed to provide the evidence to convict Mulcahy.

       Mulcahy stood trial in 2000 with Duffy appearing as a witness, giving graphic evidence over 14 days.

       Mulcahy claimed he was innocent, but on February 5, 2001, was given three life sentences for murdering three women.

       He received 24-year jail terms on each of seven counts of rape and 18 years each for five conspiracies to rape, to run concurrently.
