No. But it's entirely possible that he didn't take the girls back to his house. Many people assume that his victims must have screamed and someone would have heard. That's not necessarily true. We know that Heuemann strangled the 4 Gilgo victims. Screaming is nearly impossible in that scenario. We also know that all 4 of the victims were known drug users, so it's not out of the realm of possibility that he drugged them first. We also know that Melissa Barthelemy's phone was traced to two hotels in Massapequa on the night of her murder...a Budget Inn and The Best Western.

Cellphone records for Ms. Barthelemy traced the calls, which were to her voicemail, to two motels near Massapequa, the Budget Inn and the Best Western , according to the law enforcement official, who spoke on condition of anonymity because the investigation is continuing.
Now, there's nothing to say that Melissa herself was at these hotel rooms, but her phone certainly was. So it's not beyond the realm of possibility that some of these girls COULD have been taken to motel rooms and murdered there.
