  We have carried out $JHK_s$ imaging of 12 white dwarf debris disk candidates
from the WIRED SDSS DR7 catalog, aiming to confirm or rule out disks among
these sources. On the basis of positional identification and the flux density
spectra, we find that seven white dwarfs have excess infrared emission, but
mostly at WISE W1 and W2 bands, four are due to nearby red objects consistent
with background galaxies or very low mass dwarfs, and one exhibits excess
emission at $JHK_s$ consistent with an unresolved L0 companion at the correct
distance. While our photometry is not inconsistent with all seven excesses
arising from disks, the stellar properties are distinct from the known
population of debris disk white dwarfs, making the possibility questionable. In
order to further investigate the nature of these infrared sources, warm Spitzer
imaging is needed, which may help resolve galaxies from the white dwarfs and
provide more accurate flux measurements.
