The person accused of fatally shooting conservative activist Charlie Kirk is 22-year-old Utah resident Tyler Robinson, according to five law enforcement officials briefed on the matter.

Kirk, a co-founder of Turning Point USA and an influential voice in the Trump administration, was shot and killed Wednesday during an event at Utah Valley University, a public school south of Salt Lake City, according to Utah Department of Public Safety Commissioner Beau Mason. The event was hosted by the school's chapter of Turning Point USA, a group Kirk founded that organizes and mobilizes young conservatives.
