This is the moment armed officers discovered the bodies of a mother and two of her children after all three had been murdered by her son.
Astonishing footage shows a Bedfordshire Police response team bursting into a flat in Luton after gunshots were heard on September 13 last year.
Officers are seen firing smoke grenades into the flat in case the shooter was still inside, before entering as they shout that there are three victims.
The team find the bodies of Julianna Falcon, 48, Giselle Prosper, 13, and Kyle Prosper, 16, inside the property along with spent shotgun cartridges.
But there was no sign of the fourth family member and gunman Nicholas Prosper and no weapon, leading to a critical incident being declared with him at large.
