Sept. 10 (UPI) -- The suspected shooter of conservative activist Charlie Kirk is still at large following his assassination on Wednesday at Utah Valley University in Orem, Utah.

FBI Director Kash Patel early Wednesday evening said a "subject" was in custody, but later said that the person had been released and the suspect is still at large.

"The subject in custody has been released after an interrogation by law enforcement," Patel said in a post on X made at 8 p.m. EDT.

"Our investigation continues, and we will continue to release information in [the] interest of transparency."
