Developing An Investigation Plandue Week 7 And Worth 120

Read the case below and complete this assignment. A child was playing in a local park with his brother. A car pulled up as they were leaving the playground. A man inside the car motioned for the two (2) boys to come over. The man asked the two (2) boys where the nearest convenience store was located. He then stated that he was not familiar with the area and asked the boys to show him the way and he would take them home afterwards. He also stated that he would buy them whatever they wanted if they agreed to show him. The youngest brother got into the car with the man and they drove away. The older sibling ran home and told his mother what had happened. The younger brother was not heard from that night and a report was made to the police.

The next day a body was found in a dumpster behind a local garage. It was the younger brother, who had been strangled to death and was nude. Imagine that you are the lead investigator in this case and develop a two to three (2-3) page investigation plan in which you: Outline the main steps that you would take immediately as it relates to the investigation of this case. Support your response. Propose your methods for evidence collection.

Next, predict the main evidence that you would expect to find regarding the investigation of the death of the boy and the arrest of the suspect. Support your response. Propose the main investigative techniques that you would use to investigate the murder in this case. Provide a rationale for your response.

Paper For Above instruction

The investigation of a child's abduction and subsequent homicide demands a rapid, systematic, and thorough approach to ensure the collection of crucial evidence and the apprehension of the perpetrator. As the lead investigator, the immediate steps involve securing the crime scene, collecting witness statements, initiating forensic examinations, and establishing a timeline to guide the investigation.

First, securing the scene is paramount. Although the body was found the following day, ensuring that the area behind the garage is preserved avoids contamination or loss of evidence. Police would cordon off the crime scene, document the location through photographs and sketches, and collect physical evidence such as clothing, fibers, or any items left behind. The dumpster must be examined for forensic evidence, including DNA, fingerprints, or forensic traces like fibers or hair that could link the suspect or the victim to the scene.

Witness interviews would be the next critical step. The older brother’s account of the incident provides valuable information about the suspect’s vehicle, appearance, and behavior. Additional interviews should include bystanders, park visitors, and individuals nearby who may have observed the suspect or the victim before the abduction. Ascertaining the last time the child was seen and establishing a timeline helps narrow down the suspect's movements. Collecting surveillance footage from nearby cameras can provide visual evidence of the suspect’s vehicle and actions.

For forensic evidence collection, the focus is on identifying any fingerprints, DNA, or trace evidence on the victim's clothing or at the scene. The suspect’s vehicle should be examined thoroughly, including interior and exterior, for fibers, fingerprints, or biological material, which could be compared against collected samples. Additionally, gathering DNA from the victim’s clothing, the scene, and the suspect’s potential environment makes use of STR (short tandem repeat) analysis for identification and linkage.

The main evidence anticipated in this case includes DNA from the victim and suspect, fingerprints, fibers, and eyewitness testimonies. Due to the child’s nude state and strangulation, forensic analysis of these aspects may reveal the suspect’s DNA or fibers transferred during the assault. Additionally, digital evidence such as cell phones, social media interactions, or searches for children’s toys or abduction methods could offer vital clues.

Investigative techniques should include forensic analysis, such as DNA profiling, fingerprint analysis, and fiber comparison. Crime scene analysis and reconstruction will help determine the sequence of events. Interview techniques, including cognitive interview methods with witnesses and suspects, can yield detailed and accurate information. Surveillance footage analysis can corroborate witness statements and identify the suspect’s vehicle or accomplices if any.

The rationale for employing these methods is grounded in their proven effectiveness in child homicide investigations. DNA evidence is especially critical due to its high discrimination power, linking suspects conclusively if a match is found (Scheck et al., 2014). Eye-witness testimonies can fill in gaps regarding the suspect’s appearance and behavior, while forensic evidence can establish a physical linkage to the crime scene. Combining investigative techniques enhances the probability of successful case resolution, ensuring justice for the victim and accountability for the suspect.
