Homicide: Is the Caller the Killer?
The one-day basic course is designed for police officers, detectives, supervisors, and prosecutors who investigate and prosecute homicides, as well as emergency dispatchers. The course highlights the indicators made by individuals during 911 homicide phone calls that suggest guilt or innocence. Each indicator is thoroughly defined, discussed, and exemplified by actual 911 homicide phone calls. One third of all murderers call in their own crime pretending to be innocent, and much can be learned about the offender and offense from a critical analysis of the taped call.
The one-day advanced course is designed for police officers, detectives, supervisors, and prosecutors who investigate and prosecute homicides, as well as emergency dispatchers. The advanced course utilizes the 911 COPS (Considering Offender Probability in Statements) Scale to further identify linguistic variables in 911 homicide calls. Actual 911 calls from homicide cases will be examined, including the Caylee Anthony case. Students must have previously attended the “Is the Caller the Killer” basic course.
These classes are presented by Lt. Tracy Harpster who has spent over nine years analyzing 911 homicide calls and has developed a model which indicates offender probability. He has co-authored several articles on the subject and presented his research throughout the country.
