Gunman kills 3 co-workers

A DISGRUNTLED worker embroiled in a pension dispute with his company walked into the plant and opened fire yesterday, killing three people, wounding five and sending frightened co-workers scrambling into closets and to the snow-covered roof for safety.

Police said the gunman, identified as 51-year-old Timothy Hendron of Webster Groves, a St Louis suburb in the US, showed up at Swiss-based ABB Group's plant yesterday morning, armed with an assault rifle and a handgun.

Multiple St. Louis-area media outlets were reporting that Hendron was believed to be among the dead, but police refused to confirm that.

The motive for the shooting wasn't immediately known. But in 2006, Hendron and other ABB workers sued the company over retirement losses.
