Charged hadronic four-body decays of D0 mesons have been studied in the E687 photoproduction experiment at Fermilab. Branching ratios relative to the D0 → K-π+π+π- decay mode for the Cabibbo-suppressed decays D0 → π-π+π-π+, D0 → K-K+π-π+ have been measured and the first evidence of the D0 → K-K+K-π+ decay mode is reported. An analysis of the D0 → K-K+π-π+ resonance structure is also presented.
