The man accused of fatally shooting his wife outside of the South Sioux City police station last year intends to use an insanity defense.
The attorney for 41-year-old Bei Sheng Chen filed notice Wednesday in Dakota County District Court of his intention.
A pretrial conference is scheduled Friday.
Authorities say Chen shot 33-year-old Mei Huang on September 6th in the parking lot of the South Sioux City police station.
She died later at a Sioux City, Iowa, hospital.
Chen has pleaded not guilty to first-degree murder and other charges.
In December a judge approved Chen’s request to undergo psychiatric evaluation.
