furthermore, serial crimes are the easiest to develop geographic profiles, since each crime contains new spatial information and provides additional data including the fact that crime area tends to enlarge with an increase of comfort and confidence. the initial hunt and criminal acts are most likely to occur relatively close to the location of the offender's home or workplace. as the success rate increases, there will be a burgeoning sense of confidence to seek his prey further from home and to travel a greater distance. crimes that are suitable for analysis are those that are predatory in nature and exercises some spatial decision-making process such as the area for hunting targets, travel routes, mode of transportation and even body dump sites.
