MINNEAPOLIS (AP) — Prosecutors plan to dismiss murder and manslaughter charges against a white Minnesota state trooper who fatally shot Ricky Cobb II, a Black motorist, as Cobb tried to pull away from a traffic stop, saying the decision comes in response to recent statements from the trooper’s attorney and new analysis of video from the scene.

Hennepin County Attorney Mary Moriarty filed a notice to dismiss the charges after Trooper Ryan Londregan’s defense team revealed prospective testimony during an April court hearing that the trooper believed Cobb was reaching for a firearm — and that a Minnesota State Patrol trainer said he never instructed officers to refrain from shooting into a moving vehicle.

The evidence would have made it impossible for prosecutors to prove that Londregan’s actions were not an authorized use of force by a peace officer, the county attorney’s office said in a statement released Sunday.
