Farmer Brown Crime Investigation

Physical evidence left behind at a crime scene plays a crucial role in reconstructing the events that took place involving the crime. Bloodstain pattern analysis (BPA) is a discipline which utilizes the sciences of biology, physics, and mathematics. Bloodstain interpretation may be accomplished by direct scene evaluation and/or careful study of scene photographs in conjunction with detailed examination of clothing, weapons, and other objects regarded as physical evidence. The location, spreading, and appearance of bloodstains and spatters can be useful for interpreting and reconstructing the events that produced the bleeding. An investigator or bloodstain pattern analyst can decipher from individual bloodstains the direction and angle

While investigations were going on to determine how victims died, there was a discovery of fibers on the victims’ bodies. The goal of the investigator was to determine if any fibers in Wayne Williams home or person matched those fibers found on the victims. Williams denied killing

blood on O.J.'s Bronco door, on the console, on the interior side of the door, a

The blood looked like it was coming out of Ms. Garcia's head and there was a table lying by her head as well. There were some pills and a syringe lying by Ms. Garcia´s stomach area. Additionally, there were tennis shoes with footprints on them and some white powder was found at the crime scene as well. The team then analyzed all of the evidence to figure out Ms.Garcia's manner and cause of death. The analysis of each evidence took the team one step closer to finding out how exactly Ms. Garcia

16. You have become a member of a hot shot Criminal Investigative Team in the Phoenix police department. You are asked to lead your first murder investigation, but the only clues are old blood spots of the victim found near his body and blood on the clothes of a suspect. Because the main suspect is about ready to leave the country, you are asked to at least provide preliminary evidence that the blood found on his shirt could match that found at the crime scene so an arrest warrant can be issued quickly. You amaze your colleagues by simply looking through a microscope and determining from the nuclei of the red blood cells on the suspect’s shirt that, based on this evidence, he is unlikely to be guilty. How could you be so sure of this conclusion?

During this trial there were three invalid forensic sciences used in the trial (National Registry).  The investigators of this event found soil, hair, and imprints from Barnes truck that were somehow related and similar to Simon (Drahl). Pagliaro, a lady conducting evidence from the scene, had told the jury that she found the fabric from Simon's jeans matched an imprint on Barnes' truck.  She also said that there were two hairs in Barnes's truck that were more microscopically similar to the victims than to Barnes (National Registry). This evidence could lead to bad things for Barnes because it looks like Barnes is now more closely related to the

We know this because we were tested for the blood type of the blood from the glove, it turned out it was type AB. We also tested all of the employee's blood and Chris was the only one with Type AB blood. Only .6% of people have AB- blood and only 3.4% of people have AB+ blood, so the likeliness of an unknown suspect breaking into the house with AB blood are pretty slim (“Your AB- Blood is Important”). Finding out Chris is the only employee with type AB blood is the most compelling piece of evidence. Another process that can find out who the blood belonged would be a blood DNA test (“Use of DNA in Criminal Investigations”). The right side of the glass patio door was broken into and Chris right handed. He also said he lost his gloves when the investigators questioned him. Although, the piece of evidence is not so compelling because all of the employees said they lost their gloves. Chris said he was home watching t.v during the time of the robbery. Though that piece is irrelevant because all of the employees said they were watching t.v during the time of the robbery. In conclusion, Chris robbed the Clodhoppers and our conclusion is irrefutable being he is the only employee with type AB blood, mean he is the only one who could have broken into the the home and left his bloody

Through mistakes made within the investigative process of the case, the outcome of the case was affected. On the collection of evidence many pieces were contaminated causing flaws in this evidence. When packaging blood swabs the cotton swatches used were packed in plastic bags and then left in a hot truck. This blood was also contaminated as the technician who handled it still had the blood voluntarily given by Simpson on his gloves (Jones, 2009). Degradation of missed blood, which was left for three weeks after the initial run through, may have turned unusable by the time investigators examined it. It was weeks after finding the socks at O.J. Simpson’s house that the police noted the blood on them. Destruction of evidence may have been caused through the bodies not being taken to be autopsied till 10 hours after they were found. During evidence collection the majority was compiled by a Junior Detective, who was taped dropping blood swabs as well as wiping tweezers with dirty hands, this made the evidence highly contaminated (Deutsch, 1995). To conceal the body of Nicole Simpson a police officer place a blanket over the body, this was done to

According to this article the publisher jumps back in forth about what happened or what was done. But after seeing news coverage on tv and reading into depth on this subject I believe the publisher is incorrect on a few points.

Next, the investigators come rushing over to the body and snap photos of her, which can be used later on in their investigation. The investigators process the crime scene and find a lot of valuable evidence, such as DNA, fingerprints, fibers, hairs, and a footprint, all to be used in court. These people are known as forensic scientists. In a few months the forensic scientists have found a suspect, James Petty, from all the evidence,

We are here to present our evidence for The Case of the Murdered Mayor. We think that Matthew Maloy killed Mr. Robert Burlington. We looked at 5 things including blood type, hair analysis, fingerprints, tire impressions, and entomological evidence. We got 4 pieces of blood-covered evidence. The victim's blood, the victim's car, the cabin Robert was killed in, and the tire iron that killed Robert. All four of the pieces had B+ blood on them. The only suspects with B+ blood are Timothy Taylor and Matthew Maloy. Chris Cunningham had A-, Pam Preston had AB-, Timothy Taylor has B+, Vic Velto has AB+, Nicole Burlington has A-.

On the morning of September 2, 2003, Sarah Johnson, at age sixteen, shot and killed both her parents, Diane and Alan Scott Johnson. This crime occurred in Bellevue, Idaho, in the Johnson’s home with a Winchester rifle. At approximately 6:20 am, Sarah came into her parents bedroom and shot her mother in the head through the blankets, killing her. Next, Sarah moved into the master bathroom and shot her father. Investigators believe that Alan Scott Johnson, Sarah’s father, was emerging out of the shower when he was first shot.

At the Bundy crime scene police found the bodies, Brown's, amassed in a pool of blood bigger than her body, and Goldman's, his shirt pulled over his head as if to keep him from helping Brown. Of the nine blood samples found on the property six were a match to

Blood is the most widely recognized, and maybe most critical, type of confirmation in criminal behavior. There's not a viable alternative for it, whether for therapeutic or legal purposes. Its vicinity dependably interfaces a suspicious and casualty to each other & toward the “scene” of the wrongdoing. Bloodstain designs inform a great deal concerning position and development amid the wrongdoing, who struck whom to begin with, in what way, and what number of times. one to three in legal Cases, Blood consumes dependably remained careful period proof, however the possible is for customized Blood writing, and equal nowadays, criminological serologists can furnish affirmation with some solid likelihood gauges connecting a solitary separate, and

Here we cotton swabbed every inch of clothing on the victims and checked if there was a presence of blood. Using the Kastle-Meyer blood test we add drops of Ehtyl alcohol which increase the sensitivity of hemoglobin and then added a few drops of phenolphthalein which eliminates oxygen, if it’s exposed to oxygen then it will turn pink. When exposed to oxygen it means hemoglobin is present. After sterilizing all cotton swabs and repeating the procedure we noticed that reveille fur and maroon flash shirt had a presence of blood and the bikerman had no blood.
