The suspect in the killing of Charlie Kirk is being held at the Utah County Jail, Spanish Fork, Utah.

Utah's governor says the suspect is believed to have acted alone and the investigation is ongoing.

The man accused in the Kirk assassination had earlier expressed to family his opposition to the viewpoints of the conservative activist.

That's according to Gov. Spencer Cox, who announced an arrest in a targeted killing that raised fresh alarms about political violence in the United States.

The suspect was identified as 22-year-old Tyler Robinson.

Cox on Friday also cited as key pieces of evidence engravings on bullets found in a rifle believed used in the attack. Calls to telephone numbers listed for Robinson in public records ring unanswered.
