According to newly released transcripts of the videos obtained from a source close to the investigation, Nikolas Cruz details how he will carry out the shooting.
Investigators discovered the videos on Cruz's cellphone, which was taken into evidence after the shooting. The videos are listed on the prosecution's discovery list. Authorities didn't say when the videos were recorded.
WPTV has chosen not to publish the videos in their entirety without context – because to do so would only play into what this disturbed teenager wanted.
A father of one of the victims told a south Florida newspaper today that he won’t watch the videos. He doesn’t want to “see the delight he took in planning the murders of our children.”
"Hello, my name is Nick and I'm going to be the next school shooter of 2018," says Cruz at the start a video.
A Broward County grand jury indicted the 19-year-old Cruz in March on 17 counts of premeditated murder in the first degree and 17 counts of attempted murder in the first degree. A judge entered a not-guilty plea on Cruz's behalf during his arraignment.
Broward County prosecutors have said they plan to seek the death penalty despite his attorney's offer of a guilty plea in exchange for a life sentence.
If a jury condemns Cruz to die, it will take years for the execution to be carried out.
At age 19, he would be the youngest death row inmate in the state.
Florida has 347 people on death row, and has executed 96 people since 1976. So far this year, the state has executed one person.
