On a tedious Thursday afternoon, the body of an extrusive racketeer named Fannin was found at Ernie’s Lunchroom by police officers. A testimony of the only witness, the proprietor and the only employee, Ernie has said “The murderer had leaned against the wall while firing at point-blank range”. There is also one imprint of the supposed homicidal murderer on one of the walls and the cash register had just been rung up at $8.75. The police believe that person C is the murderer from the hand position of the utensils/hand positions, the relation among persons B, D, and E, and the identification of the Y and X footprints. The victim of this heinous crime is also controversial and the media are portraying Fannin as a criminal due to his reputation of racketeering. Maybe Fannin did deserve what came to him but still the public ought to know the real culprit without no prejudices from the media.
One reason the police believe that person C is the murderer is
Still people, including I would respond by saying that person A could had been a customer who might had not been threatened and therefore left to the character without no hesitation. Since I proved that persons B, C, and D knew each other they must had not been afraid and would had reacted calmly.
The police believe that person C is the murderer from the identification of the Y and X footprints. For example, the y footprints belong to a person who mopped and later went to the cash register, the only employee was Ernie. This shows that Ernie couldn’t had murdered Fannin.
There you have it folks, person C is the criminal. In conclusion the police believe that person C is the homicidal murderer from the hand posture of the utensils/hand positions, the association among persons B, D, and E, and the distinguish of the Y and X
One anthropologist stated that the evidence supported the theory that the skeletal remains belonged to potential victim #1. Therefore, the prosecution argued that the skeletal remains were that of Robert Rutherford, who went missing four years ago. It is known that the victim and the defendant had some misunderstandings about the hunting area and fought to hunt certain places in the area. On the other hand, another anthropologist stated the opposite and the defense argued that the skeletal remains did not belong to Robert Rutherford, but instead were that of Stephen Morton, who hunted in the area and went missing two years prior to Robert Rutherford. Stephen Morton had no known connections to the defendant, therefore concluding him innocent in the defense’s mind. There are some various similarities found in the case that could point in either the defense or prosecution, therefore the case needs to be revaluated for a third opinion.
We were presented with many facts that all pointed to Mr. Washburn as the murder. In the house all of the entrances were thoroughly inspected by authorities, and they found no sign of ransacking. “[They] examined all the locking mechanisms, all the doors and windows. In [their] opinion there was no evidence of any forced entry” (P.81). When police looked for fingerprints, “They were all of the Washburn family and the maid” (P.81). There was no trace of an outside party; somebody usually in the Washburn house committed the murder. While in the living room, an officer found a drop of blood. The evidence technician was called the next night to run some tests. “He sprayed the living room carpet with luminol. It is a luminous spray, and when it comes in contact with blood it illuminates” (P.82). To both men’s surprise the whole living room was illuminating. After spraying further the men found a trail from the living room through the kitchen to the garage. In the closet the men found a wet mop, which was tested for blood and also came back positive. Somebody tried to clean his or her bloody mess, and try to save himself. The physical evidence proves the killer was somebody who was familiar to the Washburn household.
This morning October 8th 1965 at about 5:13 am the body of Bob Sheldon was found lying next to the park fountain he was seen to be in a pool of blood. His body had a single stab wound in his back which had pierced his heart, killing him instantly. Supposed eye witnesses say that a small boy who was a member of the "Greaser Gang" attacked and killed Bob and intended to kill the rest of them. Cherry Valance claims that she was walking with Johnny and Ponyboy after the movies when Bob approached them in his car and threatened the two them. Be on the lookout for the two boys with the description of one that has long light-brown hair, green eyes, and is about five feet tall and another has long jet-black hair, large black eyes, and is about four feet six inches. The first one is considered to be Ponyboy and the second one is considered to be Johnny. The two are now on the run they were last seen at a party with Dally. Investigators report that Dally says he has no idea where these two are but he thinks that they are going to Mexico. A woman was taking a walk through the park and discovered the bloody corpse she said “I was hesitant at first because I thought they were watching me, but I gained some courage and called 911” the friends that were their helping Bob bully the 2 said they were there during the homicide, but decided not to call the police because they were drunk and they were scared after seeing him dead. They said, the murderer was a 16 year old boy named Johnny Cade.
That night, many witnesses reported having seen a man changing the tire of his van and waving any possible help away angrily while others reported seeing a woman wandering around the side of the dangerous highway. More witnesses reported that Kenneth and his wife were having many violent disputes at their home that usually resulted in Kenneth pursuing an angry Yvonne around the block. The most compelling evidence against Mathison, however, is purely scientific. Detective Paul Ferreira first noticed that the extensive blood stains inside the Mathison van. After hearing Mathison’s original account, he summoned the assistance of famed forensic expert Dr. Henry Lee to analyze what he thought was inconsistent evidence. Blood stains on the paneling and the spare tire in the cargo area reveal low-velocity blood stains meaning that the blood probably dripped from Yvonne’s head onto the floor. The stains found on the roof and steering wheel were contact transfer patterns probably caused by Mathison’s bloody hands. Blood stains on the driver’s side of the van were contact-dripping patterns which indicate that Mathison touched the inside of the van multiple times before and after moving his wife’s body. The final groups of blood stains on the instrument panel of the van were medium-velocity stains which show investigators that Mathison probably struck his wife at least once in the front seat causing the blood to fly from her open head wound. The enormous amounts of blood inside the van lead prosecutor Kurt Spohn to investigate the Mathison case as a murder instead of a misdemeanor traffic violation.
Jennifer Thompson-Cannino was raped at knife point in her apartment. She was able to escape and identify Ronald Cotton as her attacker. The detective conducting the lineup told Jennifer that she had done great, confirming to her that she had chosen the right suspect. Eleven years later, DNA evidence proved that the man Jennifer Identified, Ronald Cotton was innocent and wrongfully convicted. Instead, Bobby Poole was the real perpetrator. Sadly, there are many other cases of erroneous convictions. Picking cotton is a must read for anybody because it educates readers about shortcomings of eyewitness identification, the police investigative process and the court system.

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.

The most crucial evidence found to help in investigating is at the crime scene. Numerous fragments are exposed to prove Bruno Richard Hauptmann as guilty. One of the many pieces of evidence used against Hauptmann was a ladder that was left at the crime scene. As one of the investigators p...
The officers tampered with evidence and made a false discovery that he was the person and that is how he was convicted (Innocent Project N.D.). Many forensic methods have been implemented in research when looking for evidence, but the methods that are not scientific and have little or nothing to do with science. The result of false evidence by other means leads to false testimony by a forensic analyst. Another issue with forensic errors is that it is a challenge to find a defense expert (Giannelli, 2011).

Just as insight into the mind of the artist may be gained by examining and comparing the progression of his work, so knowledge of the mind of the serial killer can be ascertained by an examination of his canvas: The murder scene. Forensic profiling is the attempt to do just that. An investigator tries to discern information about the killer based on the information at the crime scene, deducing information about the cause from the effect. This is not an exact science, and has been often likened to an art. It is the goal of this work to provide the reader with a basic understanding of the function and application of forensic psychology, as well as an explication of some of its strengths and weaknesses.

Many of us enjoy watching crime scene investigation shows, but in the criminal justice system forensic investigation is an essential field that requires upright observations and a prodigious interpretation. Under forensics, it is difficult to blame someone without scientific data. For that reason, Larry K. Gaines author of the textbook Criminal Justice in Action explains the importance of Blood Spatter Analysis. Specialist can learn a great deal about violent crime by examining where blood landed at the scene, the size and consistency of drops, and the pattern of blood spatter (Gaines, 2011). Consequently, an article of the Blood Spatter Analysis will be used to explain the research methodology the author uses to proceed certain investigations.
