The search for William Tyrell continues as extra resources from around the state have been sent to Kendall, south of Port Macquarie on the NSW mid-north coast.

The boy was wearing a Spider-Man costume when he disappeared from the balcony of his grandmother’s house on Friday morning. He was last seen playing with his sister.

Three-year-old William Tyrell was last seen wearing a Spider-Man costume and playing in the front yard of a relative’s home at Kendall, south of Port Macquarie.

State Emergency Service (SES) volunteers, police and members of the local community have spent the past three days searching for him, and rescue teams spent Sunday night combing bushland calling out his name.

Police have said they could not rule out the possibility he was abducted.

Police divers have searched dams and waterways, and trail-bikes and horses have spent hours searching scrub near the house where he disappeared from.

Superintendent Paul Fehon from the Mid North Coast Command said on Monday morning they had hoped to have found William by now.

“With any situation like this, we do have an investigative capability and that capability is conducting inquires in regards to possible … any other aspects of where young William may be,” he said.

“We’re openly minded at this stage to anything, but as time passes, that window does diminish.

“At this stage we’ve still got the window of opportunity for survival. Whilst we have that we’re gearing up to continue to search.”

William’s family has expressed how grateful they are for the community’s support.

“The family are very distraught and upset but they do wish to pass on their gratitude to all the volunteers and also the emergency services that have been here especially over the weekend,” Superintendent Fehon said.

“We saw a wonderful rally of community support to be out there and to search for young William and they’ve shown their gratitude or expressed their gratitude in respect of that community rally.”

Family friend Nicole spoke to the media on behalf of the Tyrells.

“The family are devastated, and they just desperately want William home,” she said.

“William is a much loved and cherished little boy.

“If anyone out there has seen this little boy, knows anything about William, where he is, we just urge you please to contact the police.

“The family want to extend a heartfelt thankyou to all of the police, the SES, every volunteer, every community member that has come together over the last few days to help with the search.”

Police have urged anyone with information to contact them.

Police have also urged anyone with information about William’s whereabouts to contact them.

“We’ve covered in excess of 10 square kilometres and that’s predominately due to the large amount of volunteers that have come forward from the community,” he said.

“It’s been quite amazing to see how much support there has been to try and locate this young boy.

“We’re moving towards an area most probably between one to one-and-a-half kilometres from the last known location where he was seen.

“We’ve got new relief crews coming up from as far as Sydney this morning so we’ll be starting with fresh eyes.”

“At this stage we’ve still got the window of opportunity for survival. Whilst we have that we’re gearing up to continue to search”

Anything is possible: searchers

Local residents armed with torches spent the night searching for the boy.

“We’ve searched the drains on the road, but there was nothing there,” said one woman who was with a group of friends.

The group then searched a nearby abandoned home after one of them heard noises.

“[A] neighbour used to live in this house but she’s now in a nursing home so it’s been abandoned for a while,” she said.

“You know, anything’s possible.”

Among those involved in the search is Jake Casser, a tracker who lives on the NSW Central Coast.

“I feel like it’s my responsibility with the knowledge that I’ve got to come and look for this young fella in particular. My heart really goes out to the family,” he said.

“I’ve got a young daughter, 11 month old daughter and I sort of put myself in the shoes of the family.

“(I) thought if there was someone out there that had skills like I’ve got, it’d be really wrong of me to not even take time of work and come out here and make sure that I try and look for this young fella.”
