CDMS II data from the 5-tower runs at the Soudan Underground Laboratory were reprocessed 44 with an improved charge-pulse fitting algorithm. Two new analysis techniques to reject surface45 event backgrounds were applied to the 612 kg days germanium-detector WIMP-search exposure. An extended analysis was also completed by decreasing the 10 keV analysis threshold to ?5 keV, to increase sensitivity near 8GeV/c2. After unblinding, there were zero candidate events above a deposited energy of 10 keV and 6 events in the lower-threshold analysis.
