The Central Criminal Court has heard of Garda efforts to resuscitate Ashling Murphy after she was found.
Gardaí have been giving evidence before the jury of 9 men and 3 women, which heard of distressed phone calls to the station on January 12th, 2022.
33-year-old Jozef Puska, of Lynally Grove, Mucklagh, Co. Offaly, has pleaded not guilty to Ms. Murphy's murder.
The jury heard evidence of Gardaí who arrived at the scene where Ashling Murphy's body was found.
Garda Tom Dunne said he and his colleague Gda Shane Hunter alternated applying CPR for around 10 minutes.
The court heard she had a phone and SEAT car keys in her pocket and a necklace around her neck which said Ashling.
Also giving evidence, Detective Sergeant David Scahill said he noticed wounds on her neck.
He said it took four people to bring the body from the ditch to the path along the Grand Canal.
The jury also heard after using a defibrillator, there were no signs of life, so paramedics stopped working on her body and she was pronounced dead a short time later.
Pathologist
State Pathologist Dr. Sally Anne Collis conducted a post mortem examination of Ashling Murphy at Midlands Regional Hospital in Tullamore on the 13th of January 2022.
She said it was her conclusion that Ms Murphy died as a result of stab wounds to the neck, with no contributory factors.
Dr. Collis said she found at least 12 sharp wound injuries – caused by a knife or a similar instrument.
She told the court that there were also some injuries to Ms. Murphy’s fingers.
She said they may have been defensive in nature as Ms. Murphy may have held up her hands to try and protect herself.
