Utah Valley University students Zach Zimmerman, second from left, and Lauren Simons embrace during a vigil for Charlie Kirk in Orem, Utah. Spencer Cox on Friday announced the arrest of a 22-year-old suspect in the fatal shooting of conservative activist Charlie Kirk after the man confessed to family members. Some of the more obscure and idiosyncratic engravings Cox described suggest the suspect was steeped in online and video gaming subcultures. Violence is violence. Many lined up with flowers, candles and flags and placed them before a memorial with a larger-than-life photo of Kirk.
