Family attorney Carl Crews asked for a fair trial for Johnson.

"Timothy did not have any due process. All he had that late night in February was him and the officer. He was judged and executed and decided Timothy did not have a right. But let me tell you this. There will be justice for Timothy in the end."

Commonwealth's Attorney Steve Descano requested a rare special grand jury look at the case.

The only other time Descano sought a special grand jury was in the case of another fatal police shooting — the 2017 shooting of Bijan Ghaisar by U.S. Park Police officers after a stop-and-go highway chase. The charges, in that case, were ultimately dismissed by a federal judge.

Shifflett's attorney says prosecutors should respect the decision of the initial grand jury, which did not find probable cause to bring criminal charges.

A special grand jury works with different rules than the first grand jury.

It will give the commonwealth's attorney more power over the proceedings.

Prosecutors will be allowed to stay in the room during testimony, and they will also be able to question the officers who testify.
