Criminal charges are being considered in relation to the death of a 39-year-old woman in a collision on the M50 in Dublin.
Jacqueline Griffin, from Tallaght, died after the incident on the Junction 5 slip road in Finglas last January 24.
Her mother, Frances Griffin, provided a DNA sample to gardai, which was analysed by a forensic scientist as part of the formal identification process.
The woman's family appealed to the public not to share images of the fatal crash following her death, after pictures appeared widely on social media.
The collision involved a number of vehicles, including a truck.
The family did not attend the opening of an inquest into Ms Griffin's death at Dublin Coroner's Court, but a deposition from her mother was read out.
Frances Griffin said she gave a DNA sample to gardai last January 25.
Det Gda Sarah Jane Connolly took the samples to Forensic Science Ireland and asked for these to be tested for comparison as a matter of urgency.
A post-mortem examination gave the cause of death as head injuries due to a road traffic collision.
Insp Bronagh O'Reilly told the coroner a file is being prepared for the Director of Public Prosecutions (DPP). Det Gda Connolly applied for a six-month adjournment of the case to allow time for the DPP to consider the case.
Coroner Dr Myra Cullinane adjourned the inquest until January 16.
