A preliminary hearing has concluded in the case of a conservative activist's killing. The prosecution sought to demonstrate sufficient evidence to move forward with a trial. A 23-year-old man is charged with aggravated murder and could face the death penalty if convicted.

The defendant chose not to testify during the hearing. His lawyers presented a final witness in an effort to cast doubt on certain evidence. They had previously questioned the reliability of certain tests and opposed the release of a recorded interview.

Further details about the case and the hearing are available, including the next steps and potential rulings from the judge.
