Portland police say Johnson ended up shooting himself in the testicles. Officers arrested him nearby.
The 41-year-old man told a judge on Tuesday that he was “deeply ashamed” of wounding a friend in the leg last January in the course of a robbery. He asked for leniency but was sentenced to 20 years.
The Oregonian reports the man was convicted of shooting someone in San Francisco in 1994 and someone else in Multnomah County in 2006 - both over drug disputes.
In this case, a jury convicted Johnson of robbery, assault and possession of methamphetamine.
