A police officer at the university where prominent conservative US activist Charlie Kirk was killed last year testified on Monday that he saw what looked like a “sniper pad” atop the building from which the fatal shot was fired.

Kirk’s widow Erika Kirk sat during Monday’s preliminary hearing just a few feet away from Tyler Robinson, the man accused of driving four hours from to kill Kirk, 31, last September. Members of Robinson’s family also were present.

Kirk, a co-founder of the conservative youth organization Turning Point USA, was credited ⁠with energising many young voters behind Donald Trump in his campaign to regain the presidency in ​the ⁠2024 US election.

The president’s son Donald Trump Jr. reportedly also attended the hearing.
