Finding Kristian Burnstad

Kristian Burnstad has been missing since February 7th, 2017. He was apparently dropped off at his parent's house in enumclaw at 1:30am and was supposedly supposed to be picked up. His parents said he never knocked or came in the house. We only know he was dropped off becashe the person said he did drop him off. 30 search and rescue volunteers along with 3 cadaver dogs searched the area near his parent's house and the lake near there but found nothing. I have talked to tons of people, been given numerous names and some rumors/anonymous tips. We are at a standstill at this point. Police have not questioned anybody. We are going to now hire a private detective to take over to do the things that I cannot do. This money goes toward funding that and even raising the reward money if possible. Please share this and if you have any recommendations, please let me know!
