Several accelerator-based and reactor-based neutrino experiments suggested the existence of a new fundamental particle, the sterile neutrino. Sterile neutrinos, unlike the electron, muon, and tau neutrinos in the standard model, do not interact via weak interaction. In this talk, I will present the latest MiniBooNE oscillation results with 12.84e20 protons on target (POT) electron neutrino appearance data and 11.27e20 POT electron antineutrino appearance data. A total electron neutrino and antineutrino charged-current quasi-elastic event excess of 460.5 +- 99.0 events (4.7 sigma) is observed. The observed excess is consistent in energy and magnitude with the excess reported by the LSND experiment with a combined significance of 6.0 sigma. Future and current experiments, especially the Coherent Captain Mills experiment at Los Alamos, to test this excess will be discussed.
