We will present the results of our analysis of Hubble
Space Telescope (HST) and deep ground-based images,
to isolate the massive progenitor stars of several recent
core-collapse supernovae (SNe). The identification of
the progenitors is facilitated in a few cases by high-precision
astrometry based on our HST ToO imaging of the SNe at late times.
