A Jacksonville man could face prison time over charges that he threatened a Secret Service agent investigating a report that he talked about killing former Vice President Kamala Harris on TikTok .

Franklin Delana Jarrell , 59, was indicted Thursday on four counts of making threats to a federal law enforcement officer, a charge that can carry a potential six-year sentence behind bars.

The indictment did not charge Jarrell with threatening Harris, but a court filing in February said Jarrell threatened an agent who contacted him about comments made online about shooting Harris.

A complaint by Secret Service Senior Special Agent John Rolander said TikTok sent the FBI information that someone using the name Dale Jarrell on the social media site who said "I will take a sniper rifle and blow her head off like they’re trying to do with Trump.”

President Donald Trump was almost killed during his campaign last year by a gunman in Pennsylvania who nicked his ear but killed another person and wounded two others.

Another comment by the same person referred to U.S. Rep. Ilhan Omar , D-Minnesota, and said “we will kill your ass,” the complaint said.

Rolander wrote in the complaint that he called a phone number linked to an email address for the TikTok account and talked with a man who said he was Dale Jarrell and that “he could say ‘whatever he wanted’ because of his ‘First Amendment Right.’”

“I advised Jarrell that his freedom of speech did not include terroristic threats and that threatening to kill the former vice president was a federal crime,” Rolander wrote. “Jarrell’s tone became more irate and he threatened to kick my front teeth in if I came to his house. He stated he has a house full of weapons and I would ‘never make it past his fence line’ if I showed up.”

The complaint said the man answering the phone hung up but then called the agent back 25 times over about five hours and left a total of 21 voicemails, including one that said "You threatened to come to my house. I want you to. I will kill you straight up.”

The agent wrote that police ran the phone number through a database to identify an address on Maple Street in Jacksonville's Westside, then contacted the owner of the property, who is the father of the man indicted last week. That triggered another call from the TikToker warning the agent not to contact his father again, the complaint said.

Jacksonville police arrested Jarrell last month.
