We discuss the formation of stellar mass black holes via protoneutron star (PNS) collapse. Such PNSs are modelled as central objects in general relativistic ID core collapse simulations with Boltzmann neutrino transport. In the absence of an earlier explosion, the PNS collapses eventually due to continued accretion of outer layers of a massive star onto the central object. We investigate the resulting conditions with respect to neutrino emission at the formation of a black hole
