Kenneth T. Toth, 33, a division manager with the Koh Management and Computer Systems Corporation of Rockville, died Sept. 14 in an automobile accident in Roanoke.

Virginia State police said the car in which Mr. Toth was a passenger was attempting to turn off a highway when it was struck from behind by a tractor-trailer and was crushed between the truck and a guardrail.

Police said Ki-Chul Koh, president of the Koh corporation, also was killed in the crash and that the driver of the automobile was injured.

Mr. Toth was a native of New Jersey and a resident of Gaithersburg. He was a graduate of Salem College in West Virginia where he earned a bachelor's degree in business administration. He earned a master's degree in automatic data processing at George Washington University.

He joined the Koh corporation in July 1981 as head of its management support division. Prior to that, he had been a computer software project administrator with the Calculon Corporation in Rockville for about five years. He also had served in the Army.

His marriage to the former Elaine Bianco ended in divorce.

Mr. Toth's survivors include a son, Glenn, and a daughter, Kristin, both of Gaithersburg, and his mother, Margaret Toth, and a sister, Karen Toth, both of Garwood, N.J.
