Smiling Nikolas Cruz described his odious plans in a cellphone video

Videos have surfaced showing Nikolas Cruz, the author of Marjorie Stoneman Douglas High School shooter, describing his plan to kill 'at least 20 people.'

The shooting, which took place on Valentine's day, February 14, 2018, in Parkland, Florida, was considered to be the most violent one in American History. Cruz, armed with an AR-15 rifle, killed 17 people and injured 15 others.

According to CNN, the Parkland shooter's footage was obtained from a source close to the investigation and might prove that the 19-year-old carefully planned the attack.

In one of the videos, Cruz can be seen wearing a green t-shirt, a hat and headphones. He starts by saying that he is going to be the 'next school shooter of 2018.'

He goes on to say that he plans on taking the lives of at least 20 people, and can be seen smiling, even laughing, while he talks about how big of an event it will be and how he will become famous.

In the footage, the 19-year-old can be heard issuing a serious threat: 'You're all going to die.' Cruz goes on by saying that everyone at the high school will feel the 'wrath' of his 'power.'

Cruz gives a possible motive for his killing spree, claiming that people called him an 'idiot,' to wish he responded by saying that people were 'stupid and brainwashed'

A girl by the name of Angie was also mentioned by the Parkland shooter. Although her identity is yet to be revealed, it is clear that Cruz had strong feelings for her since he is heard saying 'I will always love you and I hope to see you in the afterlife.'

The videos were found in the shooter's cellphone by investigators and are currently listed on the prosecution's list. Based on his actions and the evidence against him, Cruz could face the death penalty.

If that were to happen, he would become the youngest inmate to enter death row in the state's history. A total of 347 people are locked up in death row in Florida, and 96 have been executed since 1976.
