Thread for discussion of burlap, condition of remains, etc. Hopefully LE will give us more clues to discuss soon.
I wonder if the SK thought of this when he decided to use burlap:
"Human remains do have a detectable thermal signature during decomposition, explains special agent Catherine Sapp of the Georgia Bureau of Investigation, who wrote a 2008 article on aerial photography for the FBI Law Enforcement Bulletin. But that does not last long. "Once you have decomposition to the point that it's just bones, then there's not going to be anything to decompose, so there isn't going to be any heat signature," she says. Skeletal remains, on the other hand, are often highly visible to aerial photography. "Bleached-out bones will jump out at you," Sapp says
Kaytom,
That may the case with a visible spectrum or infrared spectrum camera, but I suspect the FBI now has more advanced camera technology called hyperspectral which can detect the chemical signature of human flesh and bone. The camera may even be able to find the chemical signature of burlap just by passing overhead.
Here is some info that I posted earlier on one of the other forums. I haven't been able to find much info from the web about that camera in the black hawk, but this is some of the info I did find:
I think the FBI Black Hawk Helicopter may be providing more than just "high resolution" photos. I think there camera will be able to tell you all locations where a decaying body could be found. Here are some articles regarding this technology:

A related method that is currently being developed by the FBI detects living humans, and recently dead bodies lying on the ground, by recognising the chemical signature of human skin. It could be used when trying to locate and rescue people who are lost or missing, and to track down fugitives.
Kerri Moloughney of the FBI Counterterrorism and Forensic Science Research Unit in Quantico, Virginia, and her colleagues fitted a helicopter with a hyperspectral camera covering visible and infrared wavelengths in the range 400 to 2350 nanometres to see whether skin signatures could be spotted from the air. They then flew it over a specially prepared site where human and animal remains at various stages of decomposition had been scattered on the ground, and where there were also a number of live human volunteers. The signals it picked up showed a clear distinction between living human skin and the skin of long-dead humans and animals.
Moloughney says the technique could be combined with visual aerial searches and thermal imaging to pinpoint individuals in a landscape. "We hope it will enable us to find so much more than we can currently," says Moloughney, who also presented her results at the AAFS.
Underground heat betrays decaying flesh
So much for stone cold dead. Writhing masses of maggots can raise the temperature of decaying flesh to around 30 °C - and that heat signature could provide a telling clue in the hunt for hidden corpses.
Ian Hanson at the University of Bournemouth, UK, and his colleagues have been using thermal imaging to help detect the bodies of deer carcasses laid out in light woodland. "In many dead bodies you've got a maggot mass of several kilograms feeding away inside, and they like it warm," says Hanson.
"The police view has been that once a body has reached the same temperature as its environment, you can't pick it up with infrared," says Hanson. But his team has now found that as the maggots congregate into a mass, they can raise the temperature inside deer carcasses to 28 to 30 °C. This takes around five days, depending the weather.
When maggots do colonise a body, the heat they generate can be detected by infrared cameras mounted on police helicopters, Hanson has found. This could provide a new tool for identifying bodies in the undergrowth. "Once the maggot mass has developed there's a window of opportunity to find the bodies again," says Hanson.
Official: Remains' condition delaying IDs

"The scattered distribution of human remains, some dismembered, found this year on a South Shore island has delayed genetic analysis and potential identification, a police official said Thursday."
"Forensic experts were forced to take extra samples from the dispersed remains because some of them were incomplete and it was unclear if bones found in separate locations came from the same people, Suffolk police Chief of Detectives Dominick Varrone said at a hastily scheduled presentation before the county Legislature's Public Safety Committee."
"Preparation for a potential genetic match "became very time consuming because the manner in which these remains were disposed, it could have been one or more people combined," he said. "So rather than just take one sample from each find, they have to take multiple samples."
"It still is unclear how many victims all the remains represent, but Varrone acknowledged Thursday that some of the incomplete remains may prove to be from the same person or people."
"We absolutely do not have tentative IDs," Varrone said. "We would hope the submitted DNA will produce matches, but right now we don't know if it will or it won't."

Four New Facts Revealed Today
- Head & hands found on March 29th belong to slain prostitute Jessica Taylor whose body was found in 2003 in Manorville.
- Head & hands & right foot found on April 4th belong to the other woman victim found in that same stretch of woods in Manorville.
- The toddlers body found was female about 18 to 24 months. Not ruled a homicide yet.
- Man's body found on April 4th was Asian, in late teens/early 20's and his death is ruled a homicide but "radically different".
Just found this; Burlap use mentioned by Suffolk County Parks Department
Summary of work in Warbler Woods
Summary: Commissioner Scully stated that Suffolk County Parks has done work in the Warbler Woods area since this Council met last. The PLC was not used for this project. Nick Gibbons went over the specifics of the project for Council members. He stated that the illegal bridge that was found a few months ago was removed. They brought in fill, burlap and filter cloth which was used along the west bank. The cement structures that were pulled out were used to help block illegal vehicle access. They also brought in logs and pulled down the catbriar to help keep people out of that area. He stated that due to the tremendous size of this area enforcement back up is needed to help keep the work that was done in place. He also stated that since all their work there has been continued vandalism of the shoreline protection efforts.
Warlber Woods is a section of the Carman's River in Brookville. Someone had illegally built a bridge across the small river and the Couny Parks Department stepped in to remove it.
