(Portland, OR)  --  County leaders are working to fix a computer formula that nearly released a murder suspect from the Multnomah County Jail.  Willamette Week reports the jail nearly released 19-year-old Jamaine Oliver a couple weeks ago until a sheriff intervened.  The mistake was due to an error in the algorithm that identifies potential candidates for early release to prevent overcrowding once the county jails reach 95-percent capacity.  Multnomah County Sheriff's officials say the algorithm mistakenly identified Oliver as a candidate.
