The 9th of February 2015 marked the third anniversary of the murder of Andrew.
Republican Action Against Drugs said it carried out the murder but his family have denied RAAD’s claim that he was a drug dealer.
Andrew’s mother Donna Smith claimed her son was killed not because he was involved in drugs, but for more personal reasons.
Ms Smith said the family believes that the shooting of Andrew in Lisfannon was carried out on the orders of a paramilitary figure who had a grudge of some description.
A number of arrests have been made by investigating Gardaí into this murder and are working closely with our colleagues in the Police Service of Northern Ireland.
Anyone with information is asked to contact the incident room in Buncrana at 074-932 0504, the Garda Confidential Line 1 800 666 111 or any Garda Station.
