UPDATE: Three shot to death at St. Louis plant

Three people have been shot to death and five others wounded at an ABB transformer manufacturing facility in St. Louis on Thursday. The shooting happened after 6:30 a.m. Thursday when the gunman reportedly went into the facility armed with a rifle and a handgun.

KMOX-TV in St. Louis was reporting Thursday afternoon that the gunman, identified as 51-year-old Timothy Hendron of Webster Groves, MO, had been found elsewhere in the plant with a fatal self-inflicted gunshot wound.

Three of the wounded were in critical condition and two were in fair condition, police said.

Hendron reportedly was involved in a pension benefit lawsuit with ABB.

"This is obviously a very serious situation and we are working to gather more information as it becomes available,” said a statement from ABB’s corporate headquarters in Zurich, Switzerland. "The welfare of our employees is of utmost importance to us.”
