This makes sense to me. In 2000. the torso of Valerie Mack was dumped in a wooded area near Halsey Manor Road in Manorville. Two and a half years later, he also left Jessica Taylor's torso on a pile of wood scrap off Halsey Manor Road.
The two dump sites were just half a mile away from each other. Both of the women dismembered remains were found in an area that is only 3-4 miles away from John Bittrolff's house.
One of these dump sites was on an isolated access road that is off the beaten track. This suggests that the killer has an intimate knowledge of the Manorville area.
In 2011, the police uncovered Taylor and Mack's skulls on Ocean Parkway - close to where the killer dumped the Gilgo Four in a set of burlap sacks.
So is the conclusion there are two serial killers using the same dumping ground in Gilgo....possibly. Could Bittrolff be responsible for all these murders?
From what ive read, the detectives say Bittrolff was on to them from the start after they received a hit on his DNA & started to follow him around using a fake company plumbers van hoping he would discard something they could use for DNA testing.
They stated he never threw out anything in the garbage that had used at home or in his truck....they also stated he was a beer drinker & had a lot of bottles but never threw any out, so Bittrolff definitely knew about forensic science & how advanced it had come.
As far as was he the killer using burner phones, VPN with internet & able to entice the GB4 into his web, we may never know. If he had the knowledge of updated forensic science in 2014, then he may have had the knowledge of not leaving a trace on cell phones & the internet.
He obviously didnt know about the future of DNA back in the early to mid 1990's, hence leaving his DNA on Tangredi and McNamee.
Also, imo, Shannan Gilberts death wasnt at the hands of any serial killer.
I agree with you that Shannan Gilbert was not the victim of a serial killer.
I’ve thought about John Bittrolff being responsible for all of the murders other than Shannan Gilbert, but now believe that the GB4 and Unidentified Asian male were killed by another person, Unsub.
a) the time frame
b) the modus operandi
c) the phone calls to Amanda Barthelemy
Fire Island Jane Doe, Peaches, Baby Doe, Valerie Mack, Jessica Taylor were an earlier and more random time frame. Fire Island Jane Doe 1996, Peaches and Baby Doe 1997, Valerie Mack 2000, Jessica Taylor 2003.
The GB4 and Unidentified Asian Male were a later and more patterned time frame. Unidentified Asian Male 2006, Maureen Brainard-Barnes 2007, Melissa Barthelemy 2009, Megan Waterman 2010, Amber Lynn Costello 2010.
Fire Island Jane Doe, Peaches, Valerie Mack and Jessica Taylor were all dismembered. Valerie Mack's and Jessica Taylor's remains were discovered in both Manorville and along Ocean Parkway.
The GB4 were all strangled and their bodies were all wrapped in burlap bags and placed in a similar fashion almost evenly spaced along a specific section of Ocean Parkway.
It might be safe to say that the person who killed Melissa Barthelemy was also responsible for killing all of the other GB4 victims. This person called Amanda Barthelemy from her sister's phone.
If it had been John Bittrolff could not have Amanda Barthelemy identified his voice after he was arrested?
If John Bittrolff was so careful regarding DNA and as to dismembering his victims leaving their remains in separate locations, would he be careless enough to contact the victim's sister, possibly allowing his voice to be identified?
I believe had Unidentified Asian Male had been a female that he would have been killed and disposed of in the same manner as the other GB4 victims. His estimated year of death was 2006, which fits into the beginning of the GB4 time frame. Based on the psychological profile of Unsub, I believe that Unidentified Asian Male was beaten to death by Unsub during a fit of rage, after Unsub learned that he had been duped by a transvestite.
