A county jail in Vancouver, Washington has deployed a system that will see all new inmates registered in a fingerprint database to improve tracking of their movements and records.Jail Chief Ric Bishop said at a training session for corrections deputies on the new system for Clark Country Jail that the new biometric registry will augment the jail's current procedures for tracking and identifying inmates.Using a fingerprint reader and the database, “you can verify who they are, and we'll enroll them so that if they come back, when they come in the door, finger goes on the capture device, and we'll know right away who they are,” he told jail staff, reported the Spokesman.Bishop said that the biometric system would have prevented an escape earlier this year related to identity theft.On May 12, Michael Diontae Johnson, 30, allegedly swapped clothes, ID bracelets and cells with LaQuon Carson Boggs, 19, who was scheduled to be released that day.Court records say Johnson signed Boggs' name on paperwork and recited Boggs' birthdate before walking out of the jail that morning.
