A high P_T dilepton event observed in 1.8 TeV p^^-p collisions at CDF is analyzed with Dynamical Likelihood Method. A likelihood function for the dilepton decay channel in the tt^^- production is given. We illustrate how the method can be applied to eliminate some typical Standard Model processes that could generate spurious events. By assuming that the event comes from the tt^^- production, the maximum likelihood mass and the expectation value of mass are evaluated as 124 and 136 GeV/c^2, respectively, and a mass range at the 68% confidence level is estimated to be (119, 151)GeV/c^2, including measurement errors.
