A mother and her two teenage children who were killed in a tower block flat died from gunshot wounds, an inquest has heard.
Nicholas Prosper, 18, is facing three charges of murder after his mother Juliana Falcon, 48, his brother Kyle Prosper, 16, and his sister Giselle Prosper, 13, died at their home in Leabank in Marsh Farm, Luton, on 13 September.
Opening an inquest into their deaths, senior coroner for Bedfordshire Emma Whiting said all three had been shot in the head. Their bodies were not identified until 25 September.
The inquest in Ampthill was adjourned until a later date, which has yet to be set.
Last month, Mr Prosper was remanded in custody and is due to face a plea and trial preparation hearing at Luton Crown Court on 5 December.
