From the Lawrence Daily Journal-World for July 12, 1973:
Six people were arrested this week after what Kansas Attorney General Vern Miller was calling "the largest drug buy in the state's history." The location was the second floor of a house at 835 Michigan and the transaction was $6,000 worth of cocaine, with Kansas Bureau of Investigation agents making the purchase. Three persons had been arrested at the scene and three others later on related drug charges. One of those arrested was a Kansas University student, and two others were listed by KU officials as former students. Five of the six persons had been arraigned this morning in Douglas County Court, with preliminary hearings set later this month. The $6,000 cash used in the sale had been recovered, along with the cocaine and some other drugs. Other persons were still being sought in the same series of sales, according to Douglas County Sheriff Rex Johnson.
