Murder victim Kathleen ‘Katie’ Brankin
The 37-year-old mother of one was stabbed to death on July 12 at Swanns Bridge Glamping site on Seacoast Road near Limavady.
Murder charges against her partner and killer Thomas Davidson were dropped the following month.
It came after the 53-year-old took his own life in the remand unit at the high security Maghaberry Prison on August 28.
Coroner Joe McCrisken received an update from detectives attached to the PSNI’s Major Investigation Team at a pre-inquest hearing on Wednesday, October 20.
A PSNI detective said they had prepared video statements of three main eye-witnesses who witnessed the stabbing.
In addition, there was body-worn video footage from an officer who attended the scene at the time.

Mr McCrisken said he would then obtain a copy of a post-mortem report from the state pathologist, create a witness list and set a date for inquest.
He added that the inquest was likely to start in early 2022 subject to the availability of a courtroom.
