THE 'cold case' conviction of Vera McGrath for the murder of her husband Brian is a resounding victory for justice 23 years on.
It is a major success for the Garda Serious Crime Review team which painstakingly reviewed the evidence in the case.
New technologies, including DNA, were crucial in prosecuting the case.
The cold case team is currently examining 14 unsolved murders, stretching back over 30 years.
Modern communications, such as mobile phones and emails, were not in use then and gardai must rely on other evidence.
Reviews of witnesses' evidence, the 'pricking' of consciences and new forensic methods all play a key role.
Grieving families have new hope today -- and suspects will be anxiously looking over their shoulders in the wake of this case.
