A preliminary hearing is in progress for the alleged killer of Charlie Kirk. The case involves a Utah man accused of murder. A key witness is a former police officer who claims to have seen the shooting.

He later found evidence on a nearby rooftop that suggested someone had been positioned to shoot. The officer's testimony is part of an effort to determine if there is enough evidence for a trial. Kirk's family members were present in the courtroom to hear the testimony.

Further details about the case and the hearing are available from CBS Texas.
