The person of interest in the Charlie Kirk assassination walked by several neighborhood cameras — as the FBI said — and TMZ has video that appears to show him walking toward the Utah campus where Kirk was shot … while concealing his weapon.

TMZ obtained chilling video that shows a man dressed in all black matching the description of the FBI’s person of interest hobbling down a residential street Wednesday in Orem, Utah at 11:49 AM … heading toward the Utah Valley University campus just a couple of blocks away.

Remember, the FBI has said the individual arrived on campus at 11:52 AM.

It’s interesting that the man is hobbling … law enforcement says they recovered a bolt-action rifle — a Mauser .30-06 — at the scene, and it looks like he may have the rifle hidden under his clothing, hence the hobbling and strange gait.

After the shooting, as the campus is being cleared, you see students walking in the opposite direction … and in the background — in an unpaved area behind some homes — there’s someone dressed in black running through someone’s backyard.  Everyone else is calmly walking down the paved road away from the scene.

There’s a manhunt underway for the shooter, and the feds have been asking for help from the public … and this video certainly seems important.
