HANOVER, VA (WWBT) -The Hanover Sheriff said they'll search until they find Robbie Wood, Jr. no matter how long it takes.
This will be the third night for Robbie in the woods.
But trained professionals will hike during the overnight hours, hoping to track down the little boy so many are praying for.
The search site for the hundreds of people looking for Robbie, who's been away from his family now for three days, is more than 2,000 acres.
"This experience is heart-wrenching for all of us. I can not imagine their level of distress," said Hanover Sheriff David Hines.
Troy Tyree joined the trained professionals just this morning.
"We start at 89 on the road," said Tyree.
Tyree and his team of about 50 walked through a horse farm and property of a nearby rock quarry.
This grid search started on Verdon Road and stretched more than a mile into the thick, rugged brush to the North Anna River.
Quarry staff alerted searchers to the hazard.
"As you get to the back portion of the parcel the terrain steeps down pretty aggressively," said a quarry staff member.
Robbie vanished Sunday while on a family outing in the North Anna Battlefield Park.
Sheriff Hines says the 8-year-old with autism can't verbally communicate and awareness of his personal safety is non-existent, a challenge for searchers retracing his steps.
Bloodhounds hit on his scent in the park.
"Robert was last seen at the end of the trail close to the North Anna River," said Sheriff Hines.
Tyree is setting his emotions aside and not dwelling on the fact that Robbie has no food or water for survival.
He's in it for the long haul.
"I'm hoping the little fella is back. Who knows what's going on in there, but you've got to hope," said Tyree.
The search will go into the night. The Virginia Department of Emergency Management will be in the woods looking for Robbie.
Today alone, not counting the volunteers, there are more than 300 trained professionals involved in the search.
