Airspace Structure; Procedure
We received a call for [medical] transport of a patient to ZZZ. Due to radar returns showing heavy rain approaching the ZZZ area; I replied that we could take the patient to ZZZ1 hospital; but not to ZZZ. I was aware of a TFR over the ZZZ1 area earlier during the day; but that TFR expired at XA:24 local time. Upon receiving the call; I verified on the FAA TFR website that the TFR was not still active. It did not show up on the FAA TFR Map website; on the Weathermeister website; or on Foreflight App on the iPad. However; the following morning the TFR was in effect once again; effective XJ:05 local to XU:00 local. Since; unknown to me;  the cause of the TFR still existed during the flight; I believe the TFR may have been in effect during my flight; but it was not shown on even the FAA TFR-map website.Because I believed the TFR to be non-active during the time of the flight; I did not contact approach to obtain the proper transponder code to penetrate the TFR. We did successfully transport a patient having a medical emergency to ZZZ1 hospital.
Helicopter pilot believes that he may have passed through a law enforcement TFR; during a patient transport; that did not show up on any web sites or the Foreflight app on the iPad.
