HiRes data led to the observation of the GZK cutoff. A direct implication of this observation is that cosmogenic neutrinos should exist. We use injection of protons from a uniform distribution of cosmic accelerators to generate input z dependent input spectra that are then propagated through the CMB and fit to the observed monocular spectra on earth. Each accelerator injects the same power law spectrum, and z evolution of the accelerator population is modeled as (1+z)$^m$. We present the resulting neutrino and gamma ray fluxes at the highest energies.
