Crime Scene Investigators have concluded the blood on Mr. Browns jeans are human and the same type as the victim (O-). The test results are indirect evidence that implies Farmer Brown’s jeans were in contact with O- blood at some unknown point in time. Therefore, the evidence is circumstantial and only provides reasonable suspicion that Farmer Brown may have been involved.
Crime Scene Investigators recommend completion of a DNA test to confirm the O- blood on the jeans is consistent with the DNA in Mrs. Brown’s O- blood and investigate if Farmer Brown was wearing the jeans at the time of the murder. Crime Scene Investigators plan to review additional collected evidence for physical and/or trace evidence left by Farmer Brown at the crime scene.

If trace evidence from the crime scene, direct evidence such as a witness to the crime, or Farmer Brown confesses then the criteria for probable cause would be met and crime scene investigators support arresting and charging Farmer
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-.
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
On April 13 at approximately 10:00pm Rupert and Rupina Clodhopper returned home to find their back patio door had been broken into. The police questioned them about the $10,000 in jewelry the kept in a wall safe. They said only six of their employees, Mike, Bob, Chris, Mary, Susan, and Jessica, knew about it. The police evidence technician team found broken glass and a glove with blood on it. The glass was from the glass window pane of the patio door. Each employee was then asked about their whereabouts during the time of the robbery and to give blood samples. The purpose of this lab is to find out who broke into the Clodhoppers home by testing the blood samples from the employees and the glove. Analysis:
Boquete was charged with burglary and attempted sexual battery in December of 1982 and January of 1983. At trial, the victim recognized Boquete as the criminal. Boquete guaranteed that he had been home the whole night with his family, watching sports, until he went to the store with his cousins. Police had gathered the casualty's underwear and pajama top at the scene where the crime was committed, and an analyst affirmed at trial that both had semen on them.The casualty told police that she was certain that the semen had come from the culprit. The investigator led blood type testing on the proof that uncovered Type A blood and different spots on the victim's clothing demonstrated no blood group markers. He affirmed that both Boquete and the victim were Type O non-secretors (which means their blood classification cannot be recognized from organic liquids). The Type A blood should have cleared Boquete as a identified criminal, however the examiner did not say he was excluded. Rather, he said the spots without any markers could have originated from Boquete and 20% of the
The sock was important because it appeared to have blood stains on it. For the prosecution’s case against Simpson, they had the blood stains analyzed by the Department of Justice serologist Gary Sims. He testified in the case that the blood found on the socks were what he considered to be “spatter stains or something along those lines” (Walraven, 1995). The blood was tested and was found to be a match for one of the murder victims, Nicole Brown Simpson. To counter this evidence, the defense for O. J. Simpson called Herbert MacDonell to testify about the blood stains that were found on the socks in Simpson’s bedroom. The defense wan’t trying to deny that the blood belong to Nicole, but rather how the blood ended up on the sock in the first place. Based on his experience in the field of bloodstain pattern analysis, he was able to present an argument that the blood stain was a result of a “compression transfer” (Walraven, 1995), rather than blood spatter, as the prosecution suggested. The compression transfer is said to be the result of someone placing blood onto the sock using some sort of device, and then removing it from the surface of the sock. The amount of blood present on one particular portion of the sock was also inconsistent with what you would find if spatter had occurred. Additionally, based on an identical spot of blood forming on the opposite side of the sock from, it was argued that the blood could have only come in contact with the sock while it was not being worn and in a relatively flat position. The theory of the sock was that the blood was planted on it, and that could have only have happened if it was not being worn at the time of the
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?

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.
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
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.
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
Their first set of evidence, and possibly the best part of attaching the three to each other that night, was the blood. There were approximately 22 submissions of blood evidence found at the Bundy Condo (murder scene), Rockingham (Simpson's residence), and in the Bronco (Simpson's vehicle). All of which were a match to either Brown, Goldman, Simpson, or a mixture of the three. All figures of the blood samples were found in the testimonies of Dr. Robin Cotton, laboratory director at Cellmark Diagnostics Inc. and Gary Sims, senior criminalist with the California Department of Justice DNA laboratory (Toobin).
After doing their job in he crime scene, the evidence they took will be taken to the forensic scientist. Crime scene investigators will look at the photographs and connect their theories based on the crime that occurred. The forensic scientists will also examine the victim’s clothes, while the medical examiner will analyze the victim’s body for more clues and evidence that they may find and they will all be doing this in the crime lab. The things they may find could be hair, fiber, semen, blood, another person’s DNA, bruises and many more. After the forensic scientists
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.
