With the increasing complexity of modern society,the occurrence of serial crimes climbed rapidly,which increased the detection difficulties for the police.Based on the survey data of serial crimes happened in Yorkshire UK,this paper analysed the buffer areas of crime places using software of ArcGIS 9.2,and established a model with Rossmo fomula to reclassify crime places.This research also gives the probable distribution of criminals' residence,and predicts the probable time and place of next crime by using the time sequence.
