ST. LOUIS A day after a 51-year-old factory employee went on a horrific shooting spree at his St. Louis company, killing three co-workers and injuring five others before taking his own life with a single shot to the chin, St. Louis police officials were still trying to determine why he did it.
“It was a gruesome scene,” Capt. Michael Sack of the St. Louis police said at a news conference on Friday. “He fired well over 100 rounds throughout the complex.”
Captain Sack confirmed that the shooter was Timothy G. Hendron, 51, of Webster Groves, Mo. Mr. Hendron was married with a 20-year-old son and had a hunting license, according to public records. Officials said he went to the ABB Power factory armed for a rampage.
He took with him one assault rifle, one shotgun and two handguns, the police said, after finding the second handgun on the scene, along with a fanny pack full of ammunition. A fifth gun was found near the guard shack in the parking lot, where Mr. Hendron first opened fire on his co-workers.
The bodies of two men were found in the parking lot on Thursday by police arriving on the scene, and two more were found inside the building, one of which turned out to be that of Mr. Hendron.
On Friday, the police released the names of the three others, and ABB released a brief statement mourning the deaths of three of its employees. The company’s statement did not mention Mr. Hendron.
Police said that Carlton J. Carter, 57, was shot once in the head and was found dead outside the building. Terry Mabry, 55, was shot once in the head and once in the leg, and was also found outside. Cory Wilson, 27, was found shot in the shoulder and the head, and was found inside the plant.
Five more people were wounded in the incident. Two were hospitalized in critical condition and two more in fair condition, while one was treated and released on Thursday, police officials said. All five of the wounded were men.
A motive for the killings was not yet clear. A neighbor of Mr. Hendron said that at one point he was a supervisor at the plant, which assembles electrical transformers. At the time of the shooting he was engaged in a public dispute with ABB Power, as one of four named plaintiffs in a class-action lawsuit filed against the company over the company’s pension fund.
According to the complaint, filed in 2006, ABB’s pension fund managers assessed fees that were “unreasonable and excessive,” and without plaintiffs’ knowledge. The plaintiffs had sought to recover financial losses, and the trial had just begun this week in federal court in Kansas City, Mo.
“He was sort of a private person, but he was always friendly,” said Glenn Meyer, 71, another neighbor of Mr. Hendron’s. “He mentioned he was having problems at work, but he never expanded on what the problems were.”
