A Utah man is accused of killing Charlie Kirk, and prosecutors are working to put him on trial for murder. A former campus police officer recently testified in the case, describing a rooftop area near the scene of the crime.

The officer found an area that appeared to have been used by someone lying prone, with markings from elbows, knees, and feet. This discovery was made after the officer witnessed Kirk's shooting while he was speaking to a crowd.

Further details about the case are available from NBC 5 Dallas-Fort Worth, including testimony from the officer and the presence of Kirk's family in the courtroom.
