In a case that has shocked Ireland and Irish around the world, Ashling Murphy, 23, was attacked and murdered when she was out for a run in Tullamore, Co Offaly on Wednesday, January 12.

Superintendent Eamonn Curley, Tullamore Garda Station, said earlier in the day on Thursday: "Yesterday, shortly after 4 pm, Gardaí from Tullamore Garda Station attended to an incident at the Grand Canal Way at Cappincur in Tullamore following a call from a member of the public.

"At scene, Gardaí discovered a young woman with serious injuries. Medical attention was provided but despite the efforts of the medical team who attended, this young lady passed away. The injuries we believe at this time are consistent with an assault.

"The incident occurred, as I said, on the Grand Canal way at Cappincur, but more specifically between Boland Lough and Digby’s bridge here behind me. This area here where the crime occurred is popular among Tullamore residents and is widely used for recreational purposes.

"The victim of this crime is Ashling Murphy a 23-year-old local lady from the Blueball area of Tullamore. Aisling was a school teacher in Durrow National School."

Superintendent Curley said that immediately following the discovery of the crime, a full-scale murder investigation was launched and the scene was sealed off.

A postmortem has been completed, the results of which are not being released for operational reasons.

An incident room has been set up at Tullamore Garda Station with more than 50 Gardaí assigned to the investigation. Personnel from Nationalist Specialist Units, including the National Bureau of Criminal Investigation, have been assigned to the investigation.

"No stone will be left unturned in bringing the perpetrator of this crime to justice," Superintendent Curley said.

He added: "At this stage, there is no information that the victim and her killer were known to each other. From inquiries we have carried out to date we believe this crime was committed by one male who acted alone."

A number of vigils are to be held in memory of Ashling Murphy between Friday and Sunday, including one at Dáil Eireann in Dublin on Friday night.
