Man gets 25 years for trying to kill police informant

SIOUX CITY, Iowa (AP) — A Sioux City man has been given 25 years in prison for trying to kill a police informant.

The Sioux City Journal reported that Isaac McDonald, 23, was sentenced Wednesday in U.S. District Court in Sioux City. He'd pleaded guilty to conspiracy to tamper with a witness by attempting to kill a person and guilty to other crimes.

McDonald shot John Mercure in the head on Aug. 1 as he passed the car Mercure was driving in Sioux City, authorities have said. Mercure, who was believed to be speaking to police about drug trafficking and firearms, survived after crashing his car into a tree.

He's the third person sentenced in the shooting.

Andrew Nissen, 24, of South Sioux City, Nebraska, was sentenced last month to 15 years and eight months. Jessica Ott, 31, of Sioux City, was sentenced last week to 15 years in prison. Both pleaded guilty to conspiracy to distribute a controlled substance and use of a firearm during a drug trafficking crime.
