Ammunition found at the scene of Charlie Kirk's murder was reportedly marked with pro-transgender and anti-fascist messages.
The FBI revealed earlier today that the gunman jumped from the building, about 180 yards across from where 31-year-old Kirk was shot in the throat, and fled into a neighborhood on foot.
Bullet casings from the used .30 caliber rifle, which was discovered in the nearby woods, were engraved with "speeches" in support of transgender ideology and Antifa, the Wall Street Journal reports.
The markings were also on the rifle, according to the WSJ.
US officials said they had tracked the suspect's movements and had video identifying him, but were conducting further investigations before releasing it.
Palm and footprint prints have been found and are being used to help track down the suspect, they said.
