Ammunition found with a weapon linked to Charlie Kirk's fatal shooting was engraved with messages linked to the right-wing influencer's political enemies, according to sources.

The Wall Street Journal reported that an internal law enforcement bulletin and a person familiar with the investigation show that ammunition found in the weapon was engraved with expression of transgender and antifascist ideology.

The .30-caliber hunting rifle was found in some woods near the scene of the shooting at Utah Valley University, and sources said the gun was wrapped in a towel with spent cartridge still in the chamber and three unspent rounds in the magazine.

All of the ammunition found in the older-model rifle was engraved with wording.

The 31-year-old Kirk was shot in the throat moments after saying there had been "too many" mass shootings involved trans people in response to a question from an audience member, who then asked the Turning Points USA head how many mass shooters there had been in the U.S. over the past decade.

“Counting or not counting gang violence?” Kirk replied, and seconds later he was struck by a bullet in the neck.

The audience member who asked the question has not yet been identified, and the shooter remains at large.
