Charlie Kirk's widow, Erika, and his parents are planning to attend a preliminary hearing next week for Tyler Robinson, who is accused of killing the Turning Point founder. 

During the week-long hearing, prosecutors plan to demonstrate they have enough evidence against Robinson to proceed with a trial, the Associated Press reported. 

The hearing is scheduled to begin on July 6. It will be the most thorough presentation of the evidence in the case so far, and it will be the first time Kirk's family has attended the proceedings. 

Prosecutors have said they intend to seek the death penalty.
