Ammunition in Kirk Shooting Engraved with Transgender, Antifascist Ideology: Sources By Sadie Gurman and James Fanelli Investigators found ammunition engraved with expressions of transgender and antifascist ideology inside the rifle that authorities believe was used in the fatal shooting of Charlie Kirk, according to an internal law enforcement bulletin and a person familiar with the investigation. The older-model.30 caliber hunting rifle was discovered in the woods near the scene of Wednesday's shooting at Utah Valley University, wrapped in a towel with a spent cartridge still in the chamber, the sources said. There were also three unspent rounds in the magazine, all with wording on them. Kirk, 31, was onstage going back and forth with a student about mass shootings involving transgender people when he was targeted, according to videos of the attack. The student has not been publicly identified.
