Initially Susan Kirk dismissed her friend and stepmother's concerns, telling the woman that she needn't worry, that Marecek and Hana were simply cousins and they were showing harmless familial affection.
That argument would become harder to support later when, in 1992, while authorities were still combing through the evidence in Viparet's slaying, George Maracek and his cousin, Hana, were married.
But even before that, there was evidence that Susan Kirk's assessment of her father's relationship with Hana was, at best naïve.
The evidence came in the form of a handwritten letter. To some degree, prosecutors contend, the discovery of that letter may have set into motion the events that led to Viparet Marecek's slaying.
