A large-scale search of bushland on NSW's mid-north coast has found no signs of missing boy William Tyrrell but detectives have gathered information relevant to their investigation.
A team of specialist officers led by the homicide squad started the fresh forensic search on June 13 in an area near his grandmother's home in Kendall, where he was last seen in September 2014.
No evidence of William was found during the operation, which wrapped up on Thursday.
But detectives have "gathered information relevant to the investigation".
The search was designed to rule out William dying in a case of misadventure.
It's understood investigators have now returned to their theory that he was snatched.
Detective Chief Inspector Gary Jubelin, who oversaw the 50-strong search party, previously said new leads had emerged from the investigation.
Deputy State Coroner Harriet Grahame spent time at the search site this week. However, the case has not been referred to the coroner for an inquest.
A $1 million reward for information that leads to the recovery of William remains on offer.
