I was born in LaCrosse and my grandparents were close friends of the Hartley's, my grandfather being a chemistry professor at the University.
My grandparents (Mr & Mrs Lawrence Rowe), along with the Hartleys, the Campbells, and others I can't remember, formed a pot-luck "supper club" that met regularly - and this is how I know and remember the Hartleys.
I can say they were both exceptionally pleasant, charmingly funny and sweet natured.
No one in my family, or anyone, ever mentioned or discussed Evelyn in front of them. I was told they had accepted the fact that she was dead and her body would never be found. They had lost another child earlier to polio, which from other stories I have been told, was another entire nightmare affecting many families and spreading fear throughout La Crosse. So the loss of a child was something they were already unfortunately familiar with.
I also know that there was extensive investigation and searching for Evelyn (or her body) at the time, and the Hartleys were vigorously involved - and that any attempt to portray the Hartleys as being disinterested, or no longer being interested in continuing the investigation, is to discredit their need for closure in mourning the loss of their daughter and moving on with their lives. I also understand that the event generated significant fear throughout the city, which remained for sometime.
Regarding rumors of what happened that night, I have heard the following theory discussed by my family: The assailant(s) were let into the house by Evelyn under false pretense of car trouble, students looking for Prof. Rasmussen, or some other sympathetic story. Evelyn was smart enough to be aware of potential danger, but kind, and it was believed that appealing to her desire to be helpful would have worked as a way of getting inside the house. It was strongly felt that Evelyn did not know the attacker(s). At some point after this an attack occurred inside the house. Evelyn looses one shoe escaping, and unable to get out of the house (or in an effort to keep the assailant(s) away from the infant), flees (or falls) down the stairs to the basement. Another fight occurs in the basement, either before, or while, Evelyn is trying to escape through the basement window. It is at this point that she is screaming and neighbors look outside and see nothing. She escapes out the basement window (possibly with stab wounds in her back and legs), and is disoriented, rapidly losing blood, possibly about to faint or lose consciousness, she steadies herself from falling leaving a bloody handprint on a house, while she zig-zags across the yards. The attacker(s) leave the house, and pursue and capture her. She is seen by a witness being taken by two people to a car and then being driven from the area. The Gein rumors were frequent - but there were also rumors that this was an act of one or two male college students engaged in a random rape attack, fraternity hazing stunt, or some such that spun disastrously out of control and ended in murder.
Anyway, I stumbled across this discussion and thought members might be interested to hear this...
