New details were released Friday into the shooting death of Boede Paul.
In a press conference on Friday morning, Twin Falls County Prosecuting Attorney Grant Loebs released more information from the investigation behind the officer-involved shooting on Jan. 16.
Paul had alcohol in his system, though investigators weren't sure if that played a major role in the situation.
They also said Paul fired two shots at officers, and nine officers returned fire.
One officer's gun malfunctioned, and the other eight officers fired between 65-75 shots. Three of those shots killed Paul.
Officials said these investigations take so long because of the detail-oriented work.
No charges will be filed.
The Bannock County Sheriff's Office said Boede Paul told detectives that he had killed his girlfriend, Angelea "Leah" Schultz, a mother of two. He also told police where he had buried her.
Deputies spent hours on Jan. 16 trying to talk Paul out of his pickup in the area near Reservation and Philbin roads, and he left the vehicle several times, but finally exited it with a gun and shot at officers. Nine officers returned fire -- eight from Bannock and one from Bingham County -- and Paul was killed.
The investigation into the standoff was headed by Sgt. Nathan Diekemper of the Pocatello Police Department. Investigators submitted a report to the Twin Falls Prosecutor's Office for its determination as to whether there should be any criminal charges filed in the shooting, said Twin Falls Prosecutor Stephen F. Herzog in a news release.
Twin Falls County was reviewing the officer-involved shooting as part of an established protocol between Bannock and Twin Falls counties.
In a news conference in January, Bannock Sheriff Lorin Nielson had said officers do not enjoy it when they have to shoot the someone.
"We don't become police officers to kill people. We become police officers to protect people," he said.
In the press conference Friday, Nielsen said his officers have all seen a professional that specializes in police matters. He made sure to make note that, while 65-75 shots seem like a lot, the officers had automatic weapons.
The Schultz investigation is still open, according to Bannock County Prosecuting Attorney Steve Herzog, but he said it is close to being complete.
