Goods 850-5:: A z>4 galaxy discovered in the submillimeter?

We report an SMA interferometric identification of a bright submillimeter source, GOODS 850-5. This source is one of the brightest 850 mu m sources in the GOODS-N but is extremely faint at all other wavelengths. It is not detected in the GOODS HST ACS images and only shows a weak 2 sigma signal at 1.4 GHz. It is detected in the Spitzer IRAC bands and the MIPS 24 mu m band, however, with very low fluxes. We present evidence in the radio, submillimeter, mid-IR, near-IR, and optical that suggest GOODS 850-5 may be a z > 4 galaxy.
