00:00Overnight, authorities releasing new videos showing Charlie Kirk's suspected killer
00:04in the moments immediately after the shooting at Utah Valley University.
00:08You can see the suspect run across a roof as he flees the scene.
00:12He's going to climb off the edge and then drop down to the ground.
00:16As he did that, he left some palm impressions.
00:20There's some smudges, some places we're looking to collect DNA.
00:23There's a shoe imprint.
00:25The video then showing the suspect running across the parking lot, approaching a street.
00:30Police say after the video cuts out, the suspect ran into the woods
00:33where investigators say they found a high-powered rifle wrapped in a towel.
00:37Sources say three unspent cartridges were recovered,
00:40containing markings that are now under investigation.
00:43Other clues include a footprint on the roof
00:45and impressions that investigators believe are from the shooter's palm and forearm.
00:50The lab at Quantica, the FBI lab, they have the latest technology in DNA extraction.
00:55And obviously, they're really pros at finding partial or complete prints of some sort.
01:02So that's going to help them maybe identify him if he has prints on file.
01:08Authorities say they've received more than 7,000 leads and tips in this case,
01:11the most since the Boston Marathon bombing.
01:13And they've conducted more than 200 interviews.
01:16But they're pleading with the public to look closely at these images of the suspect.
01:20Please pay close attention to the t-shirt, like I said, very distinctive with that American flag
01:25and that eagle, the hat with the triangle and the sunglasses.
01:29Another video obtained by TMZ shows a figure who appears to be the gunman approaching the campus.
01:35Sources say based on the long distance from where the shot was fired,
01:39from an elevated position and the low-tech nature of the rifle,
01:42the shooter likely had considerable experience with firearms.
01:45Despite no suspect in custody, President Trump yesterday blaming the left for Kurt's death.
01:51We have a radical left group of lunatics out there, just absolute lunatics,
01:56and we're going to get that problem solved. I'm only concerned for the country.
02:00Just hours after the shooting, the president condemning political violence
02:03while listing the attacks on Republicans,
02:06not mentioning the recent attacks of Democrats in Minnesota
02:09or the attempt on the life of Pennsylvania's governor.
02:12I think it is dangerous when the president cherry-picks which political violence he's going to condemn
02:18and which he's going to allow to just simply pass.
02:22I think we need to be universal in condemning all political violence.
02:27Authorities now warning about more messages online pushing for violence.
02:31What we're seeing is our adversaries want violence.
02:33We have bots from Russia, China, all over the world that are trying to instill disinformation and encourage violence.
02:43Amid outrage over graphic videos online, TikTok now vowing to remove images of Kirk's shooting.
02:48While in Arizona, Charlie Kirk's widow returning home with her husband's body,
02:53escorted by Vice President J.D. Vance, who described Kirk as a true friend.
02:57And the FBI is offering a $100,000 reward for information leading to the arrest of Kirk's killer.
03:04You want to stay with ABC News on air and online for the latest on this investigation.
