Prosecutors have released interrogation footage of the suspected Marjory Stoneman Douglas High School shooter, Nicholas Cruz, punching himself and speaking of a “demon” voice instructing him to “burn, kill, and destroy”.
The video contains the same material as a transcript made public days earlier.
Authorities say both were edited to remove what a was a direct confession by Cruz to the massacre that killed 17 people in Parkland, Florida.
The hours of video show Cruz and Broward Sheriff's Detective John Curcio in a police interrogation room.
Much of their conversation focused on what the 19-year-old Cruz insisted was a voice that told him things like “burn, kill, and destroy.”
He said “it started when my mum passed… I hear it every day.”
Cruz also mutters “kill me” when Curcio is out of the room.
A sheriff leading the state commission investigating the massacre has said the suspect's behaviour before the shooting was a “roller-coaster,” where Cruz would have stretches of good conduct before it deteriorated.
