We report the results of two signature-based searches for new physics using 1.9- 2.0 fb-1 of data collected at the CDF experiment. Both analyses look in events containing a photon, a b-tagged jet, and missing transverse energy. The first search requires an additional jet. The second search requires an extra electron or muon. No significant excess of events over the Standard Model prediction is observed. We also describe the "CES/CPR" method which is used to estimate the amount of mis-identified photons.
