SIOUX CITY, Iowa (AP) – Authorities say seven people have been arrested in Sioux City, suspected of aiding a man who shot a police officer. A spokesman for federal prosecutors, Tim Duax, on Wednesday declined to identify the seven or address the specific charges against them.

Jamal Dean, the man who shot officer Kevin McCormick, fled Sioux City after the April 29, 2013, shooting. He was arrested five days later during a traffic stop in Riviera, Texas, 105 miles from the Mexican border.

Although McCormick’s police vehicle was riddled with bullets and he was shot in the head, he wasn’t seriously injured. He’s returned to work. Dean later pleaded guilty to attempted murder and was sentenced to 25 years in prison.
