'Burn, Kill, Destroy': Parkland Suspect Interrogation Video Released

WARNING: Disturbing content.

Chilling footage of the Parkland shooting suspect being interrogated just hours after the shooting shows him answering questions about the massacre that left 17 people dead.

Nikolas Cruz, 19, opened fire at his former high school, Marjory Stoneman Douglas in Florida, on February 14 this year, killing 14 students and three staff members.

He has been charged with 17 counts of premeditated murder and 17 counts of attempted murder.

Prosecutors have now released hours of interrogation footage, showing an agitated Cruz in a hospital gown talking about the voices in his head.

"What do the voices tell you to do?" asks Broward Sheriff's Detective John Curcio.

"Burn, kill, destroy," Cruz replies.

"Burn, kill destroy what?"

"Anything."

At one point, he raises two fingers to his head. "Kill me," he mutters. "Just kill me."

Cruz was interrogated for 11 hours in the immediate aftermath of the Parkland shooting.

Prosecutors released a heavily redacted, 216-page transcript of the interrogation earlier this week, after a judge ruled that non-confession portions should be made public.

Entire pages of the report are blacked out, but the interview repeatedly talks about the voice in his head, which Cruz says is male, his age, and is his "bad side".

The wide-ranging interview also covers the death of both of Cruz's parents, his former girlfriend, his brother, his social isolation, drug use, his history of shooting animals, self-harm, suicide attempts, and guns.

Cruz tells Curcio that he bought the AR-15 because it was "cool looking".

At one point, Cruz's 18-year-old brother Zachary is allowed to come into the room.

"People think you're a monster now," Zachary tells him.

"A monster?" he replies.

"You don’t have anything and you’re not acting like yourself. Like, why? … This is not who you are. … Why did you do this? … Don’t even laugh at me,” says Zachary.

"I'm sorry, dude," says Cruz.

Prosecutors announced in March that they will be seeking the death penalty.
