The state of Utah is expected to charge 22-year-old Tyler Robinson today. His first court appearance will be this afternoon in Provo, Utah, which will be virtual. He is expected to be charged with aggravated murder, which carries the possibility of the death penalty.
Utah's Governor said Robinson is not talking to authorities, but his family and live-in boyfriend, who is said to be transitioning to female, are cooperating.
Investigators are poring over a mountain of evidence, including the suspect's DNA reportedly found on a towel wrapped around the murder weapon and on a screwdriver on the Utah Valley University rooftop, from where the shots were fired.
"We are very interested in how much time he spent on campus, how he got there, when he got there," said Beau Mason, Utah Commissioner
