Colmuba McVeigh was abducted and murdered by the IRA in 1975

A Catholic bishop has appealed to the Irish Republican Army to identify the spot where they buried a teen-age boy 40 years ago.

The plea was made at a special Mass on Wednesday’s evening near a remote area where six searches from 1999 to 2013 failed to find the remains of Columba McVeigh.

The 17-year-old from Northern Ireland disappeared from Dublin in 1975.

Decades later, the IRA admitted killing and secretly burying McVeigh and more than a dozen other people who vanished without trace in the 1970s and early 1980s.

Bishop Liam McDaid called on IRA members to pass information to a British-Irish commission searching for unmarked IRA graves.

He said the McVeigh family’s anguish is “deepened almost beyond imagination by the fact that they have no grave to tend, no place to grieve.”
