Kurtis Hildreth, 18, came to Alaska after graduating high school. He was living with his aunt’s family in Wasilla to get a head start on the next phase of his life. But Hildreth’s life didn’t get a new beginning in the Last Frontier — it ended abruptly, the young man found dead inside his room, a pipe filled with the synthetic drug known as Spice and a lighter, on the floor next to him. His family believes the drug killed him. But the state medical examiner and Alaska State troopers aren’t sure.
