Aiden Fucci Pleads Not Guilty in 'Vicious' Murder of 13-Year-Old Florida Cheerleader Tristyn Bailey

Aiden Fucci, the 14-year-old that was accused of murdering 13-year-old Tristyn Bailey by allegedly stabbing her 114 times, pleaded not guilty on Thursday.

According to WJXT in Jacksonville, Fla., the public defender representing Fucci submitted a written not guilty plea, which was accepted by the court.

The not guilty plea now moves Fucci's scheduled arraignment in St. John's County Court from June 10 to July 28, according to WJXT.

Prosecutors previously upgraded the charges against Fucci and filed a motion to try the 14-year-old Florida boy as an adult with premeditated first-degree murder.

During a press conference last week, R.J. Larizza, state attorney for Florida's Seventh Judicial Circuit, said, "It's a sad decision, and a sad state of affairs. But it was clear to us after we looked at what happened, that it was not only appropriate to charge the defendant as an adult, but it was really the only choice that we can make."

"I hope that parents will learn something from this, this vicious and brutal murder, and that is that you need to know what your kids are doing and what they are saying," Larizza said during the press conference. "Because while we might not be able to stop these brutal and vicious murders from happening, we ought to at least try."

Bailey was first reported missing by her family on May 9 and her body was discovered by police just a day later in a wooded area near St. Johns, Fla.

Fucci was arrested a day later and identified by deputies with the St. Johns County Sheriff's Office. According to a press release from the St. Johns County Sheriff's Office, Fucci was taken into custody after "admissions during questioning," and the discovery of Bailey's body.

After Fucci was taken into custody, police said that they were investigating his social media posts, including a photo that Fucci took of himself in the back of a deputy's vehicle and wrote, "Hey guys has inybody (sic) seen Tristyn lately."

During a press conference on May 28, Larizza said that Fucci "had told friends that he was going to kill someone and that it was imminent— within the next 30 days or within the month."

"He indicated to witnesses that he was going to kill someone by taking them in the woods and stabbing them, which are certainly the facts of this case," Larizza added.

Larizza also noted that an autopsy of Bailey's body indicated that she suffered 114 stab wounds.
