(CNN) A Florida man has been charged for threatening to commit a mass shooting after his ex-girlfriend alerted authorities to a series of ominous text messages he sent her.

25-year-old Tristan Scott Wix was arrested on Friday in a Winn-Dixie parking lot in Daytona Beach Shores, the Volusia County Sheriff's Office said in a news release.

Volusia County Sheriff Michael Chitwood said on CNN Sunday that Wix had sent the texts to his ex-girlfriend, who showed the messages to authorities.

"When you look at this kid's background, he is the profile of a shooter," Chitwood said. "He lost his job, he lost his girlfriend, he's depressed, he's got the ammunition and he wants to become known for being the most prolific killer in American history."

Wix, of Daytona Beach, wrote about wanting to open fire on a large crowd of people, the sheriff's office said. "A good 100 kills would be nice," he wrote in one message, adding that he already had a location in mind. So far, Wix has not told investigators where he wanted to carry out the shooting, Chitwood said.
