Mrs McConville, a widow and mother of 10 children, was abducted in December 1972 from her flat in the Divis area of west Belfast and shot by the IRA.
The 37-year-old's body was recovered on a beach in Co Louth in August 2003.
Police have said that in the mid to late 1990s a man rang the McConville family and told them he had been involved in the abduction.
He said he was a teenager at the time and that he been told to steal a van which was used to take Mrs McConville away.
He told the family he drove Mrs McConville to a house in another part of west Belfast before he left.
The man said he had moved to England shortly afterwards and only found out later that Mrs McConville had been murdered.
Detectives from Serious Crime Branch are appealing to this man, or to anyone who may know him, to contact them.
He was around 16-years-old in 1972, from west Belfast and later moved to England.
