A search for Supergravity squark and gluino decays into di-leptons is presented. A novel search strategy of optimizing kinematic thresholds at each point in the three dimensional space of m0 -m1/2 -tan β is employed. The model space is randomly scanned using a parameterized fast Monte Carlo. No events are observed above Standard Model background in 107.6 pb-1 of Tevatron data collected by the D0 detector between 1993-96. Exclusion contours are presented in the m0 -m1/2 plane. At the 95% confidence level, a lower limit is set on the mass of gluinos of 129 GeV/c2 and on the mass of squarks of 138 GeV/c2 for all tan β < 10.
