The last scene to be searched isn't necessarily a direct crime scene but it could provide our team with some valuable information as to the motive of the two shooters. If consent is not given from parents, I would like to obtain search warrants for both the homes of the shooters. In that search warrant I would hope to obtain all the belongings of both shooters and sift through everything to try and find an explanation for their actions. The most important things I hope to find are personal items such as phones, computers, diaries, lists, or notes that will possibly show motive. Also, it is important to figure out where these two shooters got their firearms. Are they their parents weapons? Are they stolen? My search in the N.I.B.I.N will …show more content…
I will have my second investigative team questioning witnesses while the other is collecting evidence. They will start by locating witnesses directly at the crime scene, trying to funnel out the students who did not see anything for the ones that did. This will be the first category of witness questioning. Miranda does not need to be read. I will have my team start by separating the witnesses while also making sure that their emotional and physical needs are met. I want them to start out with basic questions such as; What did you see? Around what time did it start? Can you identify the people involved? Description? Did you happen to be acquainted with the shooters? Based on the the answers my team receives from these questions, we will go from there. These questions are important because it not only builds a stronger case against the remaining shooter, but it might allow my investigators to pry deeper into these witnesses and identify people that were close with these two. This would be a major help in identifying motive. An important group of witnesses to interview is room 318. This is the room that initially saw the shooters in the …show more content…
When questioned, they explained that someone told them that Mr. Samuels was shot in the boys bathroom and they guy with the gun was down the hallway on the left. I would like to know who told them? I would also like to know if the shooters saw the two girls and weren't interested because they were after specific targets like Mr. Samuels. I will ask the girls if they knew the shooters and if they were students at the school. If they are, I will go through the same questioning I went through with the previous witnesses. What did you see? Around what time did it start? Can you identify the people involved? Description? Did you happen to be acquainted with the shooters? If they know any more information, they will be questioned further, just like the
The use of eyewitness statements and testimony’s can be a great source of information, but can also lead to wrongful convictions. Due to eyewitness testimony, innocent people are convicted of crimes they have not committed. This is why the wording of a question is important to consider when interviewing witnesses. Due to the fact that eyewitness testimony can be the most concrete evidence in an investigation, witnesses may feel they are helping an officer by giving them as much information as possible, therefore they may tell them information that is not entirely true, just to please them. This is why there are advantages and disadvantages to using open and close ended questioning at different durations of an interview. The way you word a question may impact the memory of a witness, this is because a person cannot completely memorize the exact occurrences of an event.
From a trial strategy point of view, you always start with the piece(s) of evidence you believe are most damaging to the client's case and work backwards looking for an exploitable flaw in the search and seizure procedure that would make that or those item(s) inadmissible. The further back in the series of events you can argue a fatal flaw, the more likely that the evidence and any additional materials which flowed from that particular item of evidence will be excluded. This is the practical analysis of all the times we see or hear of law enforcement arguing that there was some technical item which drew their attention and suspicion and justifies their hunch that criminal activity is afoot.
If there was no weapon found at the scene and there are other evidence clues that lead to a suspect, and if the suspect had a firearm the forensics team would get a warrant to retrieve the weapon so it could be tested. When the weapon is being tested, it will allow the the bullet have individual marks that will be compared to the ones found at the scene. All of these comparisons are done under a microscope since technology has improved and it is easier to make matches. According to Young & Ortmeier (2011) “class characteristics include weight of the projectile, direction of twist of the riffling, degree of twist of riffling, number of lands and groves, and width of lands and groves.” Even though guns from the same manufacture will never have the same riffling, lands or grove. When evaluating two cartridge casings the examiner will be looking for manufacture, the size of the firing pin as well as the location. The FBI has made a integrated ballistic identification system (IBIS) it's a database that helps crime labs with comparisons where it proves one gun being used in many crimes. In addition, gunshot residue is helpful solving crimes because gunshot residue can be chemically tested. If an individual has gunshot residue it doesn't prove he or she shot the victims, it just means that they were along the premises while the gun was fired. Another
Interview Preparation: Suspects in this case would initially be the mother because of her silence and the boyfriend, because of his overwhelming need to be protective and answer all of the questions as well as since they live with him and possibly the father since he does not. I would after arriving to the station separate the mother and the boyfriend in different interrogation rooms. I would
When the first responder got to the scene he adimatately meet the 911 caller, who lead him to a car in an apartment parking lot. The car doors were closed and all of the windows were fogged. The police officer used his flashlight to see inside of the car before opening the door. He found a young African American woman who had been shot several times. The officers quickly called for backup, investigators and medical personnel. While awaiting for their arrival he secured the crime scene with caution tape, creating an initial perimeter setup as discussed in lecture two. Once everyone arrived he left it to them to search the car while he talked to the 911 caller, witnesses and others who had information on who had been present in the car. The investigators were able to collect physical evidence of bullets and cartage casings that were found outside the vehicle and inside the vehicle on the floorboard of the driver’s side. The team determined the bullets came from a 40 caliber. Other types of physical evidence that were found on the scene were the bloody clothing on the victim, the victim’s cell phone and fibers in the car from the driver’s side. personnel at the scene crime took several photographs, powered test for finger prints and did a blood spatter analysis. Stewart’s autopsy revealed that she had been shot at close range in the left hand once and in the
After contacting and interviewing all three suspects, we discovered the suspects killed the victim during a argument over a gun that had been used in an earlier robbery. Ballistics from a gun discovered in a inspection found one of the suspect suspects matched the weapon used in the shooting. The suspects were arrested and charged with second-degree murder. The case was closed and this concludes my summary of my
1. What is the difference between a. and a. Method of inquiry is based on gathering all the facts in a criminal investigation, such as physical evidence, witnesses and records (Osterburg 2010). Methods of inquiry are ways an investigator gathers the information for a particular case they are investigating. In a criminal investigation, the method of inquiry follows five simple words, who, what, when, where, and why, and lastly how. Methods of inquiry can also be very helpful when a crime scene has to be reconstructed.

Much like in Toms case, most investigations start with a crime having been committed. Forensic ballistics and firearm investigation start when there are bullets, cartridges, a weapon, or any combination of the above found at a crime scene. With the evidence, a crime lab can search for clues on these items that could lead to a suspect or possibly prove that the items were used in the crime. By comparing the markings on bullets or cartridges found at the scene with those fired from a suspect’s weapon, a ballistics expert can often determine if the rounds came from the same weapon. Just the act of cycling a cartridge through a weapon without firing it can leave permanent scratches in the case that are unique to the weapon.
Crime Scene Investigation For my assignment, I will be looking into the case of James Bulger, aged 2 years old, who was kidnapped and murdered by John Venables and Robert Thompson on February 12th 1993. Through evidence found at the crime scene and testimonial statements, the police saw that the two boys, ages 11, abducted James from Bootle Strand Shopping Center, Liverpool. They took him on a long, aimless walk where they brutally attacked him and left him for dead. In my assignment I will show how work done by the police, forensic scientists and Investigators helped to convict Jon and Robert.
Crime scene investigation is the use of physical evidence at the scene of the crime committed, also reasonable and unreasonable reasoning to gain knowledge of the events surrounding the crime. Criminal investigators pursues to establish the methods. Motives, and identities of criminal. This paper will go into great depths of how to conduct an investigation and the proper way to obtain the information. After reading this paper you should be able to know step by step how to keep notes, take accurate photos and a variety of other things that will allow you to conduct a successful investigation.
Throughout the history of America there has been a form of law enforcement present. In the 1600’s, watchmen and constables were the law enforcement officer. These positions were voluntary, and sometimes even obligatory. As time progressed law enforcement became much more time consuming and dangerous. This created the need for a twenty-four hour police force. In 1833 Philadelphia created the first twenty-four hour police department dedicated to prevention of crime and apprehension of criminals. Soon after Philadelphia created their police department, Boston and New York followed.
Throughout the year’s photo line up’s of suspects have rightfully convicted many criminals, but have you ever stopped to think that some of the witnesses may misconceive who the perpetrators actually are. I have heard of a few criminal investigations where the wrong person was incarcerated for many years because of the witness’s identification of the “suspects” photo in a line up. When I saw this topic in the FBI’s archived stories I knew I had to read it. I know that the percentage of rightfully convicted criminals are high, but there is still room for error. I knew quite a bit about this topic before I had read the article and this is why I was interested in it.
The criminal investigation process is able to achieve justice to a great to a great extent. They are effective in achieving justice, as they are able to balance the rights of the victim, offenders and society and also provide fair and just outcomes. For these reasons, the criminal investigation process is largely able to achieve justice.
We use math every day and numbers can be applied to almost anything to predict events, outcomes or even someone’s actions based on probability. Math can even help locate criminals and be an important part in criminal investigations. Criminal geographic profiling is a way to locate a hot zone of where a serial killer may potential live based on locations of crimes. Image enhancement and reconstruction is a way of enhancing a photograph enough to be able to recognize significant markings to help identify a criminal. Photos are also a source of faces and using math, facial recognition software has been developed to find a face in a database in just a few seconds. Math is often used for DNA profiling and fingerprinting matching for evidence found at a crime scene. Using math to help find criminals is an interesting concept, but most cases use math and has helped with cases in the courtroom.
