PROVO, Utah (AP) — Attorneys for the man accused of killing Charlie Kirk asked a judge Friday to block prosecutors from seeking the death penalty as punishment for comments they made in the media about a bullet fragment recovered from Kirk’s body.

The comments were made in response to speculation that the bullet fragment could exonerate defendant Tyler Robinson. Conjecture over the evidence in Kirk’s killing has fueled unsubstantiated conspiracy theories that there might have been a second shooter or that his death was staged.
