(Portland, OR)  --  Bail is set at 100-thousand dollars for a Portland man who's accused of plotting to shoot teachers at a school.  Oregon State Police say Zachariah Peterson posted messages online earlier this month, saying he had "nothing left to live for" and planned to carry out the shooting at a Christian school where he had been abused by teachers and administrators when he was a student.  Peterson is also accused of threatening children at the school.  Officials say FBI agents were able to trace the poster's IP address, leading to Peterson's arrest at his home in Southwest Portland.
