Nebraska Man Plans Insanity Defense in Slaying of Wife

DAKOTA CITY, Neb. (AP) — A man accused of fatally shooting his wife outside a northeast Nebraska police station intends to use an insanity defense. Dakota County District Court records say the attorney for 41-year-old Bei Sheng Chen filed notice Wednesday of his intention. A pretrial conference is scheduled Friday. In December a judge approved Chen's request to undergo psychiatric evaluation. Authorities say Chen shot 33-year-old Mei Huang on Sept. 6 in the parking lot of the South Sioux City police station.  He's pleaded not guilty to first-degree murder and other charges. Officials say, after hearing two gunshots outside the LEC, they found Huang on the ground and Chen attempting to escape. Huang was taken to Mercy Medical Center in Sioux City, where she was pronounced dead later that morning.
