Despite heavy rain dampening the search efforts for William Tyrrell, NSW police have extracted a new clue from the woodland area.

Officers photographed and bagged a black piece of fabric on Sunday, which was located in the same area where two pieces of red strong were unearthed just days prior.

The new piece of evidence has been sent away for testing.

On Friday, an 8x8cm piece of faded blue fabric was also photographed, bagged and sent off for forensic testing after being found near a creek in the town of Kendall.

Due to wild weather hindering the investigation, the search efforts are now expected to continue well into December.

The area that police were searching was hit with 34mm of rain, with more flash flooding predicted to hit through the week.

“The conditions here have made life very difficult,” 9News reporter Kelly Fedor told Today from the search site.”
“Yesterday police focused on clearing ground. They started digging at a new location just to the right of the main search area, testing soil depths there because the sifting and the shovelling is just so hard in this wet weather.”

Several experts have been brought in to help in the search, including an archaeologist, forensic anthropologist and hydrologist Professor Jon Olley, who found murdered Queensland schoolboy Daniel Morcombe’s remains in 2011.

Police are continuing to investigate the theory that William fell from a balcony at the home where he was last seen in 2014.

William’s foster mother is being treated as a person of interest in the case, but has not been arrested or charged.

William was just three years old when he disappeared from his now-deceased foster grandmother’s front yard seven years ago.
