PREVIOUS STORY: Man believed Trump threat would 'make him look cool'
Floyd County Prosecuting Attorney Keith Henderson said his office was contacted in the last 48 hours by the United States Secret Service about the threat believed to have originated from the Kentuckiana area. According to Henderson, Deville described how and when the threat would be carried out against Trump, as well as members of his family.
"I think the message needs to be sent that that's not allowed and we're going to hold somebody criminally liable for that," Henderson said.
Deville Sr. said his son has a history of mental illness and currently receives disability checks. He said his son had a brief stay in a mental hospital as well.
Deville Jr. has an 8-month-old daughter with his girlfriend Jackie Cox.
"He's soft hearted and he'll really do whatever for anybody," Cox said.
Cox and Deville Sr. say the mental handicap makes Deville Jr. weaker to peer pressure.
"He does this stuff to impress his friends. That's why he does it," Cox said through tears. "You know, he's slow. He's slow in the head and his friends take advantage of it."
She said she was on the phone with him before he made the video.
"I kept telling him, 'Don't do it. Don't do it," Cox said. "You can hear his friends in the background saying 'just do it. You're the one that looks tough.'"
"If you tell him, 'Richard, I dare you jump off the balcony,' he'd do it just to be your friend," Deville Sr. said.
The affidavit said Deville told police he uploaded the video because, "he thought it would make him look cool."
Cox and Deville Sr. also believe Deville Jr. was under the influence when he made the video.
The Secret Service believes he acted alone.
The threat was found by an individual, who notified the United States Secret Service office in Atlanta. According to the arrest affidavit, police tracked Deville Jr. using the IP address connected to the video he posted, which identified him and then his address.

Now, Deville Sr. says he isn't sure what he'll do without his son.
"It hurts because that's my child," Deville Sr. said. "I'm going to love my son. That's all I have is him."
Deville is charged with intimidation and unlawful possession of a firearm by a serious violent offender. He being held in the Floyd County Jail and is expected to make his initial court appearance on Friday in Floyd Superior Court.
He previously served around three years for a burglary.
