(Portland, OR)  --  More than 100 people gathered in downtown Portland last night to hold a vigil for a Black teenage girl killed by police in Columbus, Ohio.  Participants gathered at Pioneer Courthouse Square with candles and signs in honor of 16-year-old Ma'Khia Bryant.  A police officer shot and killed Bryant Tuesday while responding to a fight.  Police say Bryant was holding a knife and trying to stab two people when the officer opened fire.  The Ohio Bureau of Criminal Investigation is looking into whether the young Black teen's shooting was justified.
