CAMAS, Wash. -- The search continued Monday for a missing Camas teen last seen at school Thursday.

“It's been non-stop for anybody that's closely involved, since Thursday,” said Amy Hoffman, a close friend of the Burbank family.

Thursday is when 16-year-old Cole Burbank was last seen. A surveillance camera captured him leaving Camas High School that morning. He was on his way to Clark College for Running Start classes. He made it there, but soon after around noon, his phone stopped giving out a signal. His car, a 2010 black Honda Accord, hasn't been seen either.

“Sleep is minimal when you look at the fact that you have to find this boy,” said Hoffman, who hasn’t had much sleep since Cole went missing.

Volunteers, family and friends aren’t stopping the search and neither are Camas police.

“Over the weekend we've had at least 75-80 phone calls whether that's through 911, through the office, or through social media contacts,” said Officer Debrah Riedl, a spokesperson for the Camas Police Department.

But it was over the weekend that some people voiced frustrations about Camas police, in a Facebook group of more than 2,500 people dedicated to finding Cole.

“The main problem was we had no direct point of contact or communication with the Camas Police,” explained Hoffman.

Things changed on Monday, when Hoffman said there was a lot of communication between the police and Cole’s family.

“I feel like we've turned a corner,” she said.

Police said they've been chasing down possible leads from all over, from Depoe Bay to Bend. But in cases like this, when there's so little evidence to go off of, their hands are somewhat tied.

People have asked about getting other agencies involved. Riedl said Camas police are working with more than 10 different agencies and organizations. Some have also asked why search and rescue crews haven’t gotten involved.

“If we had a location, if we had something more narrow, that would be beneficial. But nobody has the first idea of where he might be,” said Riedl.

She said police are treating Cole's case as either a runaway or missing and endangered youth investigation. Police say they want the community to know they're doing all they can to bring Cole home.

“The thought that people think we're not helping is hurtful because we care,” said Riedl.

Riedl said Cole's name has been entered into a national database, so if an officer makes contact with him anywhere in the country, police in Camas will know about it.

Friends and family have said it's out of character for him to disappear like this.

According to the National Center for Missing and Exploited Children, there are about 60 kids missing in Oregon and around 100 kids missing in Washington. Although those numbers are probably higher because of the cases that go unreported.
