July 10 (UPI) -- A five-day preliminary hearing concluded Friday in Utah in the case of the man accused of killing conservative commentator Charlie Kirk.

The case is expected to resume with final arguments Sept. 1. Then, it will be up to District Judge Tony Graf to decide whether prosecutors presented enough evidence against Tyler Robinson to go to trial.

Kirk, a prominent far-right activist, was shot in the neck on Sept. 10 while hosting a talk at Utah Valley University.

In court Friday, defense attorneys attempted to weaken the case against Robinson by questioning the strength of DNA evidence found on the rifle prosecutors say was used.
