Armed employee opens fire at St. Louis power technology company; 3 dead, 4 wounded

3 dead, 4 wounded in St. Louis plant shooting

ST. LOUIS — Authorities now say three people are dead and four are wounded after a man armed with an assault rifle and a handgun opened fire at a St. Louis manufacturing plant.

Police Capt. Sam Dotson confirmed the number but did not have names or details about the victims.

The shooting began around 6:30 a.m. Thursday at Swiss-based ABB Group’s plant in St. Louis. Police are going room by room inside the sprawling plant, searching for the shooter and additional victims.

Many of the 40 or 50 employees inside the plant at the time of the shooting hid on the rooftop, in boiler rooms and in closets.

Fire Department spokesman Bob Keuss says at least two of the victims were in critical condition.

ST. LOUIS (AP) — An employee of a St. Louis manufacturing plant walked in with an assault rifle and a handgun on Thursday morning and opened fire, killing at least one person and wounding four others, authorities said.

Several hours after the shooting, police were still inside Swiss-based ABB Group’s plant, going room to room in a search for both the gunman and additional victims, police Capt. Sam Dotson said.

Fire Department spokesman Bob Keuss identified the suspected shooter as Timothy Herndon of Webster Groves. Dotson said Herndon is an employee of the plant.

The shooting occurred around 6:30 a.m. during a shift change, and 40 to 50 people were likely in the plant at the time, Dotson said. As shots began to ring out, employees scurried to find safety, authorities said.

“Many of them sought safety on the roof, in boilers and broom closets,” Dotson said.

Names of the victims were not immediately released. Two were hospitalized in critical condition and one was in serious condition, Keuss said. The other had injuries described as minor.

Fire Chief Dennis Jenkerson said firefighters and paramedics were standing by in case there were additional injuries, either from the shooting itself or from seeking refuge on the roof in bitter cold. The wind chill in St. Louis dipped below zero.

“It’s cold, and shock sets in, hypothermia,” Jenkerson said. “It doesn’t sound good.”

Dozens of emergency vehicles circled the sprawling plant on a day made more chaotic by several inches of snow that snarled traffic in the St. Louis region.

ABB Group makes power transmission and industrial automation equipment. The company manufactures transformers at the St. Louis site, which employs about 270 people. The company has operations in roughly 100 countries, employing about 120,000 people. Last October, ABB reported third-quarter earnings of more than $1 billion.

Thomas Schmidt, an ABB corporate spokesman in Zurich, Switzerland, said in statement Thursday that the company had received reports of the shooting.

“This is obviously a very serious situation and we are working to gather more information as it becomes available,” the statement said. “The welfare of our employees is of utmost importance to us.”

Word of Herndon’s alleged involvement in the shooting stunned his neighbors in Webster Groves, an upscale St. Louis suburb. Many neighbors described Herndon as an amicable family man who kept a well-manicured home for his wife and small boy.

“I couldn’t ask for a better neighbor. We never had any problems with him,” said Glennon Meyer, a 71-year-old retiree who credits Hendron with friendly gestures ranging from raking Meyer’s leaves to bringing over a chocolate cake last Christmas.

A few years ago, Meyer said, Hendron mentioned something in passing about having problems on the job. Hendron didn’t elaborate.

“Gee, I’ve talked to Tim many times, and he never exhibited any mental aberration,” Meyer said.

Ron Hawkins, who lives across the street from Hendron’s split-level home, echoed that.

“He seems like a really nice guy,” said Hawkins, 72. “I know nothing negative about he and the family.”
