UTAH, USA: Tyler Robinson, the 22-year-old Utah man accused of assassinating conservative activist Charlie Kirk, was charged on Tuesday with aggravated murder, a prosecutor announced, saying Robinson left behind his DNA on the trigger of the rifle that fired the fatal shot. The charge means Robinson could face the death penalty if convicted of killing Kirk last week at Utah Valley University in Orem, about 40 miles (64 kilometers) south of Salt Lake City. “The murder of Charlie Kirk is an American tragedy,” Utah County Attorney Jeff Gray said in announcing the charges.

Authorities investigate the fatal shooting of Charlie Kirk, as family plans memorial; suspect arrested, charges pending.

He adds that "much more evidence and information" will become available once charges are filed in the case.
