That he called several times for six weeks in a row indicates fairly intense obsession. That he used the term "
*advertiser censored*" in his very first call indicates the obsession involves a moral corollary. That he stopped calling after the family went public about the calls indicates publicity was definitely not one of his underlying motives. Otherwise put, this sort of behavior indicates a sadistic streak with underlying obsessive features that has something to do with "
his view" of moral behavior.
Melissa Barthelemy's sister, Amanda, who was then 15, got the first call from an unidentified man a few days after Barthelemy was last seen in New York City on July 12, 2009, said their mother, Lynn, and her fiance, Jeff Martina.
They said the last call came on August 26, soon after they told a Buffalo TV station about the calls.

Barthelemy's family faulted the police for delaying the initial search for her. But New York City police said they had begun to track her cellphone signal within a week of her being reported missing.
Missing persons launched an intensive investigation as soon as they received the case, chief NYPD spokesman Paul Browne said on Thursday.
Police tracked the signal to midtown Manhattan and searched areas near Pennsylvania Station and the Port Authority bus terminal, but the signal went dead, according to an official who had direct knowledge of the case but was not authorised to speak publicly and spoke on condition of anonymity.
Later, cellphone records obtained through a court order showed a call to her voicemail was made in Massapequa, a hamlet not far from where her body was found, on the day she went missing, the official said. ( link )
Imo, the solution to this case will rest on the first of these July 12 through August 26 phone calls in conjunction wrt where the victims went missing and were found. Excluding Maureen, 3 victims went missing within a 10 mile radius of each other. If Melissa was the killer's second victim, it is quite probable he made a mistake when he called from Massapequa. And that his later calls originating from Times Square, Penn Station, & Port Authority Bus Terminal, were designed to throw LE off... to skew geoprofiling statistical calcs.
