BOISE -- The findings of an Idaho State Police investigation into the shooting that killed an Adams County rancher are now in the hands of the Idaho attorney general.

Jack Yantis was shot and killed on Nov. 1, 2015, as Adams County deputies responded to a crash on Highway 95 in the Council area. A car had hit a bull owned by Yantis.

An ISP spokeswoman says that in the four months since then, ISP detectives have interviewed more than 40 people, examined all evidence collected, and reviewed forensic reports from various laboratories.

ISP announced late Thursday afternoon that the agency turned over its findings to the Idaho Attorney General's Office, which is acting as a special prosecutor in the case.

Todd Dvorak, spokesman for the attorney general declined to discuss the results of the Idaho State Police investigation. Attorneys at the attorney general's office will review the case before determining if any further action should be taken.

Dvorak also said there was no timeline in place for AG's phase of the investigation to be finished or released to the public.

"We're not contemplating any timeline for doing this work," he said. "We intend to take our time, and we intend to be thorough."
