We build a Geographic Profiling Model to generate the criminal's geographical profile, by combining two
complementary strategies: the Spatial Distribution Strategy and the Probability Distance Strategy. In the first strategy, we
designate the mean of all the known crime sites as the anchor point, and build a Standard Deviational Ellipse Model,
considering the effect of landscape. In the second strategy, we take many factors such as the buffer zone and distance
decay theory into consideration and calculate the probability of the offender's residence in a certain area by using the
Bayesian Theorem and the Rossmo Algorithm. Then, we combine the result of two strategies and get three search areas
suit different conditions of the police to track the serial criminal. Apply the model to the English serial killer Peter
Sutcliffe's case, the calculation result shows that the model can effectively be used to track serial criminal.
