The court documents stated that the burner phones used by Heuermann to contact the victims
constantly pinged off the same cell towers as his legitimate phone. They also pinged off the cell towers near his office in Midtown Manhattan and close to his family residence in Massapequa Park, where investigators recently discovered a plethora of eerie evidence. Records further showed that the locations of Heuermann's personal mobile and the burner phones coincided with the locations of the victims’ disappearances in Massapequa, Long Island, and Midtown Manhattan. “
Investigators could find no instance where Heuermann was in a separate location from these other cellphones when such a communication event occurred,” the court documents state.
To me it reads that after LE did cell phone tower dumps the victims phone, RH's burner phone and his own personal cell all pinged together each time.
