Controversial DNA technique is robust

[11th April 2008]

A controversial method for obtaining DNA profiles from crime scenes has been found to be 'scientifically robust', following an independent review.

'Low copy number (LCN) DNA analysis' forms a DNA profile from just a few human cells.

During the Omagh trial, it was found that a sample taken from a car bomb in Northern Ireland had wrongly been linked to a 14-year old boy in Nottingham. The Police Service of Northern Ireland subsequently suspended using the technique.

The conclusion of the latest government-funded review was that LCN DNA analysis is a sound technique, but is not currently being used as effectively as it could be. The review also recommended improvments in sample collection and interpretation.
