THE Tyrell family's heartwrenching predicament of not knowing what happened to their missing three-year-old son William is a mystery that continues to haunt the Mid North Coast community of Kendall.
It has been almost three months since the three year-old disappeared without a trace from the front yard of his grandparents' home.
Frustrated with no firm leads in the case, police have interviewed many people who were in the town on that day September 12.
The official search was reluctantly called off nine days after William was last seen playing 'chaseys' with his older sister.
The family had just arrived on the Mid North Coast after driving from Sydney and inside the home William's mother shared a cup of coffee with the children's grandmother.
Within five minutes William was gone.
Family and neighbours began the initial search.
Then more than 70 volunteers joined police searching for any sign of the youngster, who was last seen wearing a Spider-man suit.
The search party covered the adjacent Kendall State Forest and Middle Brother State Forest, nearby properties, dams and drains within a radius of the Benaroon Dr home.
Sadly, no clues were found to suggest how he disappeared.
Eleven weeks on and police say the investigation has looked at whether "human intervention" was behind the boy's disappearance.
"I can truthfully say that nothing has been discounted," Mid North Coast Superintendent Paul Fehon said.
"Our starting point was an approximate five-minute window where William has walked around the side of the house and has gone. We are still at that starting point," Supt. Fehon said.
The Facebook page Bring Little Spiderman William Tyrell Home has more than 20,000 followers and continues to raise public awareness over his disappearance.
It reads "I'm still missing please don't forget me."
William is described as having dark hair and hazel eyes.
Police say there must be someone out there who knows something about William's unexplained disappearance.
