The brutish life of AIDS victim Michael 'Mad Mickey' Devoy came to an end shortly after 10.45pm on Saturday when he was blasted three times in the head with a handgun.
Devoy had only been out of jail two days when he was murdered in Tallaght, the Herald can reveal. He was released from the Midlands Prison following a four month sentence.
The 42-year-old drug addict spent most of his adult life in prison and met the same violent death that he inflicted on Mark Byrne, who he shot dead in broad daylight just minutes after Byrne was released from Mountjoy Prison in May 2005.
It took detectives much longer to establish that it was Devoy, who suffered from Hepatitis C and HIV/AIDS, also shot Greg Lynch in the face outside a north Dublin pub last November.
The problem for the criminal was that a gang, whose overlord is crime kingpin Christy Kinahan, also found out his identity and put out a €20,000 contract on his head.
Gardai believe that this was taken up by a veteran hitman from Dundalk, Co Louth, who is also the chief suspect for targeting Devoy in a sinister pipe bomb attack 10 days ago which was first revealed in the Herald.
A senior source said last night: "This individual was a twisted evil bastard who is well known to all the crime gangs in the country."
The source added: "It is no exaggeration to say that Devoy is every bit as bad as the likes of John Dundon from Limerick – he was an absolute animal – a complete psychopath."
In November, 2006, Devoy was jailed for four years after he admitted threatening to gouge out another man's eyeballs.
Devoy from Balbutcher Drive, Poppintree, Ballymun, was only weeks out of prison for a similar offence when he told gardai that he would find Eddie McElligot in prison, slash his face with razor blades, gouge out his eyes and smash his head.
He was serving the suspended final year of his sentence imposed in May 2003 after he was convicted of issuing threats to kill John and David Cray on May 6, 2002, in a row about their rubbish bins.
