(AP) — A 1993 attack on the Frank Carlson Federal Building and U.S. Court House in Topeka still causes nightmares for some people who were working that day.

On Aug. 5, 1993, Jack Gary McKnight shot and killed court officer Gene Goldsberry. He shot at several others and threw homemade bombs before he eventually killed himself. He also rigged his car to explode in Topeka and a pickup truck to blow up in Jefferson County, where he lived.

One of the wounded, Terry Lee Morrow, says he still has nightmares. He was wounded and played dead for hours, with Goldsberry’s body lying on top of him.

McKnight was a convicted marijuana grower who was to be sentenced that day to a probable 10-year prison sentence.
