  A sterile neutrino is a well motivated minimal new physics model that leaves
an imprint in neutrino oscillations. Over the last two decades, a number of
hints pointing to a sterile neutrino have emerged, many of which are pointing
near $m_4\sim1$ eV. Here we show how MicroBooNE data can be used to search for
electron neutrino disappearance using each of their four analysis channels. We
find a hint for oscillations with the highest single channel significance of
$2.4\sigma$ (using the Feldman-Cousins approach) coming from the Wire-Cell
analysis and a simplified treatment of the experimental systematics. The
preferred parameters are $\sin^2(2\theta_{14})=0.35^{+0.19}_{-0.16}$ and
$\Delta m^2_{41}=1.25^{+0.74}_{-0.39}$ eV$^2$. This region of parameter space
is in good agreement with existing hints from source experiments, is at a
similar frequency but higher mixing than indicated by reactor anti-neutrinos,
and is at the edge of the region allowed by solar neutrino data. Existing
unanalyzed data from MicroBooNE could increase the sensitivity to the
$>3\sigma$ level.
