Juliana Falcon, 48, Giselle Prosper, 13, and Kyle Prosper, 12, were found shot dead at their home in September.

Nicholas Prosper, who also lived in the property in Luton, Beds, killed them in the early hours of the morning with an illegally owned shotgun.

Neighbours who heard gunshots at 5.30am dialled 999 but the victims were declared dead at the scene.

Armed police arrested Prosper in a nearby street and found the loaded shotgun and 30 cartridges hidden in bushes.

Detectives later discovered the 19-year-old was plotting to carry out a sickening attack on a local school.
