Scott Waddell has been charged with first-degree murder and is being currently held at the Osceola County Jail.

Corvino previously worked as a GOP staffer on Capital Hill. He later campaigned for Donald Trump in the 2016 presidential election, becoming his central Florida political director.

Cameras inside the apartment captured some of what led up to the shooting said deputies.

On one which begins around 11am, Waddell gets out of bed and reaches for his nightstand and then shoots him.

Another captured Waddell moving Corvino's body to the side of the bed in which he shot him and then staring at him for 'several minutes'.

Deputies confirmed that the alleged murder was not captured on video.

The authorities took Waddell to the sheriff's to speak where he was described as 'very cooperative and eager to talk'.

He explained to deputies that he and Corvino were watching television and drinking the night before the shooting.

Waddell, 45, told police that he could not recall harming his 'best friend' of '10 years,' adding that the two had been drinking together just a few hours before the shooting.

'He repeated numerous times he was fine but could not remember what happened before the cops showed up today at his home,' police said in a affidavit.

Weddell admitted that he suffers 'from nightmares and sometimes has homicidal thoughts wanting to kill young men'

During questioning, Weddell admitted that he suffers 'from nightmares and sometimes has homicidal thoughts wanting to kill young men.'

Waddell also claimed to be on medication due to a mental disability, the Sentinel noted.

Corvino had worked as the field director on Florida Attorney General Pam Bondi's re-election campaign in 2014 before taking a job as a regional manager for Florida Chief Financial Officer Jeff Atwater.

In a statement to the New York Post, Bondi said she was 'heartbroken' to hear the news of Corvino's death.

'Nick Corvino was a great young man who had his entire life ahead of him,' she said.
