PHOENIX (AP) — Prosecutors said Monday they will not retry an Arizona rancher whose trial in the fatal shooting of a Mexican man on his property ended last week with a deadlocked jury.

The jurors in the trial of George Alan Kelly were unable to reach a unanimous decision on a verdict after more than two days of deliberation. Santa Cruz County Superior Court Judge Thomas Fink declared a mistrial on April 22.

After the mistrial, the Santa Cruz County Attorney’s Office had the option to retry Kelly — or to drop the case.

“Because of the unique circumstances and challenges surrounding this case, the Santa Cruz County Attorney’s Office has decided not to seek a retrial,” Deputy County Attorney Kimberly Hunley told Fink Monday.

Fink agreed to dismiss the case. He said a hearing would be scheduled later to determine if it would be dismissed with prejudice, which would mean it couldn’t be brought back to court.
