KANSAS CITY, KAN. ? A gunman killed four employees of a meatpacking plant, wounded three others Friday afternoon, and was later found among the dead, police said.

Deputy police chief Col. Sam Breshears, who had earlier corrected initial reports from police that placed the number of dead as high as seven, raised the total to five shortly after 8 p.m.

Police released little information about the dead Friday night. Breshears said they included two 45-year-old males, a 21-year-old male, and two males who remained unidentified.

Breshears, who had refused to initially speculate on a motive, said initial statements from witnesses indicated the shooter was a disgruntled employee.

Police in Kansas City, Kan., received a call reporting the shooting at 5:19 p.m. A police dispatcher said an employee of the ConAgra Foods Inc. plant walked into the cafeteria and began firing. Breshears said when officers arrived the shooter was still moving through the building. He refused to answer most questions about what happened during the shooting and would not confirm the attack took place in the plant’s cafeteria.

The gunman appeared to have targeted particular workers at the ConAgra Foods Inc. plant, employee Andre Porter said.

Porter, 38, of Atchison, said he was in the men’s locker room when the gunman went in there and started shooting during the plant’s 5 p.m. shift break. He asked the gunman, “What are you doing … shooting fireworks?” Porter said he didn’t see the gun, which he described as a pistol, until the shooter slowed down to acknowledge Porter. The gunman then took off running.

Later in the 10-minute rampage, Porter said, he heard the gunman tell some people in the cafeteria, “You haven’t done anything to me, so you can go.”

Asked why he wasn’t targeted, Porter said, “He was always friendly to me and I was always friendly to him.”

One of three men wounded during the shooting was treated and released from The University of Kansas Hospital, spokesman Bob Hallinan said. One man remained in critical condition late Friday night, while the third was upgraded from serious to fair condition.

The shooting came a year and a day after an employee of a manufacturing plant in Jefferson City, Mo., shot eight people, three fatally, before killing himself.

The ConAgra plant is in an industrial section of the city, near an intersection of interstates 70 and 635 that overlooks the Kansas River, about four miles southwest of downtown Kansas City, Mo.

Bob McKeon, a spokesman for ConAgra at its corporate headquarters in Omaha, Neb., said the company was working with police in the investigation.

ConAgra is the nation’s second-largest food company. The Kansas City facility is a refrigerated meat plant.
