BATON ROUGE - A man who was arrested for allegedly killing Baton Rouge Police Sgt. Caleb Eisworth has been found competent to assist his counsel, District Attorney Hillar Moore confirmed. 

Gad Black, 41, was arrested after hitting Sgt. Eisworth with his pickup truck in a targeted attack along Joor Road on Monday, June 16. 

Eisworth died in a hospital from his injuries and Black was jailed for first-degree murder. 

WBRZ previously reported Black's arrest documents said he had a "deep-rooted hatred for law enforcement personnel."

Black was held without bond after his arrest and a sanity commission was requested.

A three-panel sanity commission found Black "presently competent" and he was arraigned in court Thursday. He pleaded not guilty. 

"You have to be able to assist your lawyer in your own defense, and can you talk and speak with your lawyer, do you know about the process and what's going on right now, and that's what was determined is that he does know what's happening, what's going on now in the system, he can speak with his lawyer," Moore said.

Moore says the next phase of this case will be for the court to determine Black's sanity at the time of the alleged offense.

"We believe he was sane at the time of the offense based on things that he did and said and the actions that he took," he said.

Because of the nature of the case -- an officer was the victim -- Moore is seeking the death penalty against Black.

Back in October, the state filed a motion to disqualify one of the doctors on the sanity commission, claiming that she is a known opponent of the death penalty. Though the court hasn't ruled on that, Moore still wants her disqualified.

"Also some other testimony that we've found that we believe it is important to her credibility, particularly in this case, that we think should be heard, and the judge indicated he would give us the opportunity to be heard on her being a part of this panel," Moore said.

Black's defense opposes the disqualification motion, stating in a court document that the DA's reasoning is not a recognized basis for disqualification.
