* On or about Oct. 7, Traitz stated he had instructed another man called before an investigating federal grand jury to "tell three-quarters of the truth."
* On or about Oct. 9, a man was threatened with being "put back in the hospital" if he did not observe a rule under which he reported having worked 100 hours each month regardless of whether he did, thereby requiring him to pay at least $60 a month in dues to the union.
* On or about Oct. 11, business agent Robert Medina, since resigned, told Traitz he was going to "call everyone in and hit them with the 100 hours." Traitz told Medina to "hit them with it."

* On or about Nov. 4, Thomas F. Brown, a former court crier hired to run errands for Roofers officials, complained he was having difficulty getting a case reassigned to the "right" judge.
* The same day Traitz and another union official discussed the "ability" of two judges, again one from Common Pleas Court and one from Municipal Court, to "influence" judges Traitz could not influence directly.
* On or about Nov. 7, Traitz, another union official and Harry Joseph, described as an alleged member of an organized crime group who sought the union's help collecting debts and "tribute," discussed the fact that Joseph Traitz "only wanted to beat people on behalf of the Roofers Union."
