Two die in factory shooting

A gunman in camouflage killed a former co-worker inside a Wisconsin factory early Monday, then committed suicide in the sprawling building, police said.

Police identified the shooter as Shadow Yang, 40, and the victim as Christina Wollenzien, 28. Both lived in Sheboygan.

Wollenzien was an assembly line worker in Rockline Industries’ coffee filter division and had worked in the same area as Yang until about a year ago, a company official said.


She was on the job Monday when she was shot to death around 4:30 a.m., police Lt. Michael Williams said. Her attacker fired one shot, hitting her in the abdomen; then, when she tried to get away, he shot her in the head, said Kirk Engholt, vice president of human resources for Rockline.
