A door security camera captured footage of the suspect in the Charlie Kirk assassination driving through an Orem, Utah neighborhood before leaving his vehicle and walking by foot on the day of the shooting.

Jessa Packard, a single mother of two who lives nearby, had a home security system that captured video of the Dodge Challenger that police say Robinson drove to campus.

After the shooting, she said, law enforcement officers descended on her neighborhood, searching yards and taking security footage.

Tyler James Robinson, 22, of Washington, Utah, was arrested on suspicion of aggravated murder, felony discharge of a firearm causing serious bodily harm, and obstruction of justice, all felonies, according to a probable cause statement filed in court and released Friday.

A judge ordered that he be held without bail.

Robinson mentioned Kirk's upcoming visit to Utah Valley University — located about 3 1/2 hours from the family's southern Utah home — at a recent dinner, kicking off a conversation about how he didn't like Kirk's viewpoints, family told authorities.

A full picture of his political leanings was still emerging.

Utah state records show he is registered to vote, but that he is not affiliated with a political party and is listed as inactive, meaning he didn't vote in the two most recent general elections.

The assassination while Kirk was speaking at Utah Valley University in Orem reverberated across the country because of his outsize influence in conservative circles, his close connections with President Donald Trump and the questions it raised about the escalating toll of political violence that has spanned the ideological spectrum.
