Erika Kirk, the widow of Charlie Kirk, and Charlie Kirk’s parents are expected to attend a week-long preliminary hearing next week in Provo, Utah, for accused killer Tyler Robinson, according to reports. Fox News says the family members are set to appear as prosecutors seek probable cause. The New York Post similarly reports that a hearing is scheduled to begin Monday morning and that Erika Kirk, along with Charlie Kirk’s parents, will be present for what it describes as the first major test of the evidence. Both outlets characterize the proceeding as a preliminary hearing in the Utah court system. The New York Post adds that close friends of the family are also expected to attend. The reports do not provide further details about the specific evidence to be addressed or the length of the hearing beyond the week-long timeframe. As of the published reports, Tyler Robinson remains an accused suspect, and the hearing centers on whether prosecutors can establish probable cause.
