LOUISVILLE, Ky. (AP) - A Louisville Zoo maintenance employee may have disabled a warning light on a small train that derailed in 2009, sending 22 people to the hospital.
That is according to records obtained by The Courier-Journal that are part of the evidence to be used in a February 2012 trial.
Plaintiffs claim the zoo was negligent in its maintenance and operation of the train.
Maintenance worker Danielle O'Mary told investigators that she saw Angel Rivera remove the bulb to an emergency warning light. She said he later asked her to lie about it.
Rivera denied removing the bulb or asking O'Mary to lie. Both employees were fired.
Records show that a warning buzzer also had been disconnected, although it is unclear who was responsible.
Zoo attorneys declined to comment.
