DAKOTA CITY, Neb. (AP) — A second mental health evaluation has been ordered for a man charged with fatally shooting his wife outside a northeast Nebraska police station.

The Sioux City Journal reports that Dakota County Attorney Kim Watson on Friday requested that 41-year-old Bei Sheng Chen be evaluated for the prosecution. That comes two days after his defense attorney filed noted that he intends to use an insanity defense.

Authorities say Chen shot 33-year-old Mei Huang on Sept. 6 in the parking lot of the South Sioux City police station. She died hours later at a Sioux City, Iowa, hospital. He's pleaded not guilty to first-degree murder and other charges.

A judge on Friday set his trial for May. 7.
