A Utah judge has postponed a ruling after a weeklong preliminary hearing and scheduled the next session for September 1 while lawyers file briefs.Prosecutors presented surveillance footage, a roommate's taped interview and DNA evidence they say links Tyler Robinson to the rifle used to kill Charlie Kirk last year, while the defense challenged forensic limits with testimony from Caitlin Oliver of the Bureau of Alcohol, Tobacco, Firearms and Explosives.Prosecutors seek the death penalty if
Tyler Robinson is convicted of aggravated murder;
Charlie Kirk's widow,
Erika Kirk, filed a motion for a speedy trial and the family attended the emotional hearing.
