Authorities have released footage of the suspected shooter in the death of conservative activist Charlie Kirk.

In the video, shown during a Thursday night press conference, the suspected shooter runs across a roof, comes down the side of a building, makes his way through a parking lot and heads towards a busy street. 

When coming down the side of the building, according to Utah Department of Public Safety Commissioner Beau Mason, the suspected shooter “left some palm impressions.”

“There’s some smudges in some places we’re looking to collect DNA. There’s a shoe imprint where we believe the suspect is clearly identified as wearing Converse tennis shoes,” he added.

Utah Gov. Spencer Cox (R) pleaded with the public for help in identifying the suspected shooter.

Kirk’s death rattled American politics, with President Trump on Wednesday saying that he was “filled with grief and anger” at Kirk’s fatal shooting and referring to him as a “martyr for truth and freedom.”

The president, in a Wednesday night video, also pledged to “find each and every one of those who contributed to this atrocity and to other political violence.”

“He fought for liberty, democracy, justice, and the American people,” Trump said in the video. “He’s a martyr for truth and freedom, and there’s never been anyone who was so respected by youth. Charlie was also a man of deep, deep faith. And we take comfort in the knowledge that he is now at peace with God in heaven.”
