to Van de Velde's office so she could look at him in person. She told them Van de Velde was not the man she saw running, and investigators didn't contact her again, sources said." Subsequently, the Jovin Task Force began hanging a sketch of this person around the neighborhood in which he was spotted. On July 16, 2008, the Jovin Task Force provided further details of Jovin's final email, written in German to a female friend, about GRE test study materials Jovin would leave for her to pick up. "Jovin wrote that she would retrieve the books and leave them in the foyer of her apartment for the classmate to pick up, giving her classmate the code to her apartment in case Jovin was not in the building." The materials were never returned, nor has anyone ever come forward as the borrower, leading many to speculate the borrower may have possibly been involved in her killing. Furthermore, Jovin's specific use of the word "someone" when referring to the borrower implies to many she did not know this borrower very well. Investigation Four days after the murder, the name of Jovin's thesis advisor, James Van de Velde, was leaked to the New Haven Register as the prime suspect in the case. Fifteen months later, criminologist John Pleckaitis, then a sergeant at the New Haven Police Department, admitted to Hartford Courant reporter Les Gura: "From a physical evidence point of view, we had nothing to tie him to the case ... I had nothing to link him to the crime." Famed criminologist Henry Lee's offer to reconstruct the crime scene was accepted by the police but not carried out. Based on subsequent questioning of the Yale community, and on Van de Velde's name being released prior to the completion of his police interrogation, it became apparent the NHPD had for undisclosed reasons become convinced that Van de Velde and Jovin must have been having an illicit or unrequited affair – a notion that friends of Jovin, including her boyfriend, considered wholly unlikely. Nevertheless, though not revealing any physical evidence or a motive, the NHPD continued to maintain that their naming of Van de Velde was not presumptuous. Yale, under the guidance of Dean Richard H. Brodhead, then chose to cancel Van de Velde's spring 1999 classes citing his presence as a "major distraction" for students, damaging his reputation and academic career. In
