Crime Scene Investigator
The identification of tactical analysis in crime patterns is a very important responsibility of the crime analyst in the country’s police agencies, as well as the world. The daily work of the analyst is to consult and extract the data in order to link them with cases that have key factors and to be able to disseminate information about the known and recent patterns discovered to the members of the police. This analysis can improve the security of the communities as the police provide quick responses to the prevention and reduction of crime. There are also different types of patterns of common crimes that are the fundamental requirement of the common elements to define a set of crimes in a pattern. Each of these types of independent defining patterns are not mutually exclusive and their frequencies overlap with mutually agreed definitions provide a consistent analysis their results are valid and reliable.
The type of analysis used in these types of cases is the tactical analysis because it involves the detection of patterns, as well as the linkage analysis for the correlations between the suspects and the crimes, in addition to their profile of objectives and their patterns of movements of the delinquents The tactical analysis links the information of the suspect and the modus operandi of a series of crimes with the motives of finding investigative clues, as well as helping to solve the crimes and cases after an arrest or detention.
- When reviewing these incident summaries, what type of analysis are you performing, tactical, strategic, or administrative, and why?
- Is this a crime series? Why, or why not?
- Crime series is a group of similar crimes that are thought to be committed by the same person or by the same group of people who act in concert.
- These cases are considered crime series since it is believed that the three robberies were made by the same people since their way of acting was the same in the three stores.
- Were there any clues that may help establish the identity of either of the suspects? If there are clues that assist in identifying offender, state what they are.
- Yes, there were clues that helped establish the identity of some of the suspects, they used the same Ford Taurus car model with temporary plates in two of the incidents. In the third incident the worker could see that one of the suspects the color of his skin was white, in addition he had a large tattoo of a spider with what looked like drops of bleeding coming out of what looked like the feet of the spider on the leg right of the individual. Another clue was that in the second and third incidents the workers saw that the suspects headed for Main Street.
- What elements of the modus operandi remained consistent in each of the three incidents?
- The elements of the modus operandi that remained consistent in each of the three incidents were: In all three incidents the suspects had firearms. The suspects wore the same type of mask in the three robberies. In addition, they used similar phrases in all three cases. In all three incidents one of the suspects jumped over the counter to take the money from the cash register. In the three incidents the suspects, when leaving each of the stores, would take cartons of Marlboro cigarettes.
- What elements of the modus operandi differed in one or more of the three incidents?
- The elements of the modus operandi that differed in one or more of the three incidents were that the hours that the events occurred were different, as well as the day and the month. Also, the locations where the incidents occurred were different. In the first two incidents the suspects ordered the workers to open the cash register and lie down for 15 minutes after they left the store, however, in the third incident the suspect took the keys from the cash register and the same put the money in the bag. In addition, in the first two incidents the suspects did not hurt the workers, but in the last incident the suspect hit the worker with the butt of the gun. In the first incident the suspects had black gloves, in the second incident the worker did not remember if the suspects had gloves as in the third incident. Also, in each incident the suspects wore different shoes with different colors. In the first two incidents the clothes of the suspects were the same, however in the third incident the suspects used different clothes. In the first incident, the video cameras did not work, but in the last two incidents the video cameras worked and captured the address where the suspects went.
- From your reading, what type of work products might you generate from this type of series in an effort to apprehend the offenders?
- The two types of work product that were used in these incidents were: North Richmond Robberies and Scottsdale Sneezy Bandit Robbery Series.
- Method of operation: Between July 25 and August 18, three incidents were carried out on the streets of South State and Main. The three incidents are identified with a similar M.O. The suspects were two men who wore a mask each. The suspects entered the stores and targeted the workers to open the cash registers to take the money. The suspects before leaving the stores took Marlboro cigarette cartons. In two of the cases the suspects used a car, fleeing from the scene to Main Street.
- Scottsdale Sneezy Bandit Robbery Series: The incidents occurred late at night in stores that open 24 hours. The description given by one of the workers in one of the stores could help identify the suspects. Also, the security cameras of two of the stores where the incidents occurred helped to identify that the suspects were moving in a Ford Taurus car with temporary plates.
We can conclude that crime analysis is one of the most effective and available tools when it comes to supporting the authorities. These three types of analysis of administrative, strategic or tactical crime play an important role since analysts provide economic and geographic information to the police agencies. They also deal with finding solutions to ongoing problems, as well as finding operational strategies. In addition to promoting rapid responses to recent crimes, providing information to police officers to identify criminal trends and arrest offenders.
