The Department of Justice has confirmed it will re-examine the garda investigation into the death of PR executive Kate Fitzgerald.
A legal counsel has been assigned to review the case following claims from her family there were flaws in the original case.
Kate Fitzgerald (25) was found dead in her home in Harty Place, Dublin City, on August 23, 2011.
It was later ruled in her inquest that the young PR executive - the former chair of the US Democratic Party Abroad in Ireland - had died by suicide.
Kate's family do not accept the verdict and have raised a number of concerns to the gardaí and the Garda Ombudsman over how the original investigation was handled.
Minister for Justice Frances Fitzgerald has since confirmed that the case would be reviewed in a formal letter to Tom and Sally Fitzgerald sent earlier this month, according to the Irish Examiner.
Due in part to evidence at the scene and to Ms Fitzgerald - who previously worked at the Communications Clinic - previously attending St Patrick's Hospital, officers initially investigating the case concluded it was a suicide.
However, it has since been claimed that a number of standard procedures used to rule out other potential causes of death may not have been followed.
