"One of the things that's a little out of the ordinary for a normal runaway is Skie did not take anything with her other than her cell phone," Forsyth said, leading police to believe the girls did not expect to be gone for long.
"It's been long enough, and nobody's heard from these kids," Forsyth said. "We're not sure what the situation is."
Crystal Sunderman said she is grateful for extensive help from the Benton County Sheriff's Office, but said she still fears the possibility of never seeing her son again.
"The most important thing of all is that wherever our kids are, whatever they're doing, if any one of them decides they've had enough, that this isn't as exciting as they thought, that they want to come home, as their parents we will do anything to get them home," she said.
"We'll protect them as much as we can from any consequences," she said. "It's more important to get them home than worrying about what's going to happen next. That's the number one thing."
