(Portland, OR) -- A Portland man with a long criminal record has been sentenced to nearly six years in prison after being convicted in a 2023 stabbing. Surveillance video showed Steven Knox chase the victim and stab him multiple times. The victim told police he knew Knox for a few years and the stabbing may have been motivated by a debt. In 1987, Knox was sentenced to life in prison for murder, and then paroled in 2009. His parole was revoked in 2011 for violations. In 2019, Knox got paroled again, despite objections from the state. Knox was found not guilty of attempted murder, but guilty of assault.
