William Tyrell’s Inquest Starts In Sydney
The NSW coroner will examine William Tyrrell's family situation and the initial response to his disappearance when the inquest begins sitting almost five years after the toddler vanished.
William vanished from his foster grandmother's home on the NSW mid north coast on September 12 2014 while wearing a now infamous Spiderman costume.
The state's top detectives have worked tirelessly to track down the missing boy since his foster mother's frantic call to police that morning - but his fate remains a mystery.
A massive brief of evidence, containing at least 15,000 items, will go before Deputy State Coroner Harriet Grahame at the launch of the inquest on Monday morning.
The first of two weeks of hearings will explore William's foster and biological families, the period of time around the disappearance and early parts of the investigation.
Throughout the investigation, William was referred to "a little boy lost" but police soon came to suspect something more sinister happened and zeroed in on known pedophiles and criminals from nearby holiday towns.
But no one has been charged for the suspected abduction.
AAP understands investigators hope the first week of hearings will show William did not wander into nearby bushland but was, instead, snatched by a predator.
In mid-2018 they conducted a large-scale search of bushland near the Kendall home to rule out misadventure and firm up their theory.
The closely-guarded persons of interest list, which ballooned to include hundreds of names over the years, has been whittled down for the inquest's second sitting in August.
Some names on that list have been previously released by police but sources say one so-far unidentified person will be watched closely when they are called in front of the inquest.
Counsel assisting Gerard Craddock SC will deliver his opening address at 10am on Monday.
