The Main Injector Neutrino Oscillation Search (MINOS) experiment has continued to collect atmospheric neutrino events while doing a precision measurement of NuMI beam nu_mu disappearance oscillations. The 5.4 kton iron calorimeter is magnetized to provide the unique capability of discriminating between nu_mu and nu_mu_bar interactions on an event-by-event basis and has been collecting atmospheric neutrino data since July 2003. An analysis of the neutrino events with interaction vertices contained inside the detector will be presented.
