A shocking event happened Wednesday, around midnight, when an employee from a plastic plant shot and killed five people, before killing himself. According to The Associated Press, officials said that the employee from Atlantis Plastics was arguing with a supervisor and, while he was leaving, he pulled a gun and shot the supervisor. Afterwards, the gunman went into a break room and randomly shot several co-workers. He came back and shot another employee and then he shot himself.

Henderson police Sgt. John Nevels said that the worker “had words with a supervisor” before his half-hour break, CNN reported. Two persons died on the spot and four others died at the hospitals in Henderson and nearby Evansville, Indiana.

Authorities said that they weren’t sure whether the man was carrying a gun or went some place else to get it. The Associated Press reported that another person was injured and was transported to St. Mary's Hospital and Medical Center in Evansville.

The identities of the victims were not made public. Also, the name of the shooter wasn’t released.

The company has 150 employees in Henderson. The whole town is shocked that something like this happened. Some of the employees were sent home after the shooting.

Atlantis Plastics produces polyethylene stretch films for wrapping pallets of materials, custom films for industrial and packaging uses and molded plastic pieces for appliances, announced a new release which was posted on the company’s web site.
