(Portland, OR) -- A man who used kids to deliver illegal drugs has been sentenced to prison. Prosecutors say 57-year-old Olaf Johnson used a 14- and 16-year-old to distribute fentanyl. Deputy District Attorney Jesse Hoffman said fentanyl destroys lives, but it doesn't hurt people on its own. He said people like Johnson using children to deliver the drugs wreck communities. Johnson was sentenced to three years in prison.
