An inquest into the death of Mark Hennessy has been adjourned following a request from the Garda Ombudsman Commission.
Hennessy - who abducted and murdered Jastine Valdez last May - was shot dead with a Garda firearm, following a major manhunt.
He'd been tracked down to a carpark in the Cherrywood Business Park in South Dublin.
Following the incident, an officer was placed under criminal investigation by GSOC, under section 91 of the Garda Siochána Act.
A GSOC spokesperson says the investigation is ongoing.
