Maryland State Police said the car Mr. Freiburger was driving was struck broadside by another vehicle when he apparently failed to stop at a flashing red light and a stop sign at Md. 273 and Md. 276 near Rising Sun, Md. The driver of the second vehicle was treated at a hospital and released.

In 1961, he moved to the Washington area as the government relations manager of the A. B. Dick Company. He left that firm in 1963 and worked for UNIVAC, the Control Data Corporation and Tesdata Systems. In 1973, he became a private consultant on government marketing. In 1977, he joined Interaction, Inc., which has its offices in Arlington, and was named its president.
