The article advises that any time a victim reports any type of "harassing" behavior, the responding officer should be thinking about the possibility of stalking. Additional inquiry must be made to determine whether this is an isolated incident or repeated conduct. The author lists some common harassing behaviors. General suggestions for investigating the stalking case are to learn as much as possible about the stalker and his/her method of operation and to corroborate stalking conduct (gathering evidence). The author also reviews the information needed to best assess the potential danger of the stalker, based upon the completion of the worksheet in cooperation with the victim. Steps for obtaining corroboration are listed, including photographing any items vandalized, damaged, written on, or otherwise having evidentiary value; checking for fingerprints on vandalized items or other objects related to stalking behavior, putting a tap on the victim's phone, and obtaining phone records from the victim's and suspect's residence. The author advises that in serious cases, surveillance of the suspect should be considered. 9 notes
