This will be confusing but I'll give it a shot...I only see the 30 calls reported on by thedailybeast, they are parroted here and there in message boards and maybe a podcast, but the only print or tv media is that single article. They are mentioned in Kolkers book but he appears to be using tdb reporting. The reporters who pinned the article (among others) are in the acknowledgments of the book. Here are the two below for comparison
Daily Beast article; (Edited for focus but in the order the quotes appeared)
Detectives and family members combed through her phone records. Lynn discovered that a few calls were made to the escort service James Bond Entertainment. Lynn's fiancé Jeff called the number and spoke to a man who told him that Barthelemy had worked with him on a number of occasions.
A few of the numbers belonged to her regular clients, one of whom was a married man who told police that Barthelemy didn't show up for their scheduled date at a motel in Jersey City.
Other numbers were traced to throwaway phones purchased in Manhattan. One of the phones was linked to the name Mickey Mouse.
Around the same time, Terry said he began to get his own taunting phone calls. His calls were from a "white guy," he said.
"He was threatening me," recalled Terry. "He said, you like to do some crazy stuff with Melissa, I know where you be at. Most of the time he seemed to be drunk. He knew who I was. He knew I had tattoos on my back. Maybe he felt [Melissa] was doing something he didn't like." Terry said the anonymous caller called him more than 30 times over a period of eight months.
Lost Girls book;
The phone calls to Amanda had been well covered in Buffalo in 2009, and the media circled back to Melissa’s family for more details. One reporter even reached Blaze, who, quoted by his given name, Johnny Terry, claimed he’d also received strange calls—about thirty, he said, over eight months—from someone he described as a “white guy.” “He was threatening me,” he said. “He said, ‘You liked to do somecrazy stuff with Melissa. I know where you be at.’ ” The police traced the caller’s number not to Melissa’s cell but to a disposable phone registered in the name of Mickey Mouse.
Which brings me to the second point in need of clarification of why did the book attribute the MM burner to the calls to john terry. That's not what TDB article states. He may have sources for this claim but it's not clear to me that he does.
My only other reason to doubt the calls were from the killer is the impression I got from listening to one of this site's radio shows from years ago when Josh and Rachel were on. Blog talk radio I believe it was. They seemed to scoff at the idea when the question was raised. It's been a while but I want to say the implications were, the calls were made from people in search of what had happened to Melissa.
I'll gladly stand to be corrected if anyone, including Bob, Josh or Rache, would like to poke their head in to clarify.
