After thorough investigations of the evidence, it seems like Maroon Flash is the person who hit Reveille while riding his bike. We used DNA evidence, fingerprint evidence, blood evidence, and hair evidence. For fingerprint evidence, we looked at fingerprints left on the notebook the cadet managed to grab from the suspect. On the cover, we found the cadet’s fingerprints, Bikerman’s fingerprints, and multiple of Maroon Flash’s fingerprints. On the pages of the notebook, we only found Maroon Flash’s fingerprints. This seems to clarify that the notebook was his, and that it was grabbed from his backpack when he hit Reveille and rode off. For blood evidence, we used the Kastle Myer Blood test; we tested for the presence of blood on Reveille’s fur, Bikerman’s shirt, and Maroon Flash’s shirt. …show more content…
Blood was found on Bikerman’s shirt, but according to his statement, which a student on the team confirms; Bikerman cut his hand playing intermural football and wiped his hand on his shirt. Another type of evidence examined was hair. Hair samples were collected from Reveille, Reveille’s handler, Bikerman, and Maroon Flash. Evidence was also collected from Reveille’s collar, Bikerman’s shirt and bike, and Maroon Flash’s shirt and bike. Reveille’s hair was found on her collar, Bikerman’s bike, and Maroon Flash’s bike and shirt. Reveille’s handler has hair that found on her collar and Maroon Flash’s shirt. Bikerman’s hair was found on his bike and shirt. Maroon Flash’s hair was found on Reveille’s collar, his bike, and his shirt. Since his hair was found on her collar and Bikerman’s hair was not, it seems to further point to the conclusion that Maroon Flash is our criminal who hit Reveille. The last type of evidence examined was the DNA evidence from Reveille, Bikerman, Maroon Flash, spots from Reveille’s fur, Bikerman’s shirt, and Maroon Flash’s
On June 19th of 1990, Robert Baltovich’s girlfriend Elizabeth Bain went missing. Elizabeth told her family that she was going to check the tennis schedules at her school, the University of Toronto Scarborough Campus. She never returned, but her car was eventually recovered. It was found with blood on the backseat, with forensic tests showing that it was Elizabeth’s. With no clear evidence, the “solving” of the case was completely based on eyewitness testimonies, which eventually had Robert arrested for the murder of his girlfriend.
Inside Lopez’ right front pant pocket, Investigator Weber found Lopez’ CA issued identification card F4297435 and a single “Toyota” car key. Investigator Weber palpated Lopez’ head and found it to be extremely soft to the touch and was very unstable. When Weber moved Lopez’ body and head, I saw a full thickness laceration approximately 4 to 6 inches to the top of Lopez’ head. Lopez’ left face was extremely swollen and it had multiple lacerations. Inside the puddle of bright red blood I saw multiple white matter tissue which based on my training and experienced, I recognized as brain matter. I asked Weber what she suspected the cause of death to be and Weber stated it was most likely due to the severe blunt force trauma to the
This case started on July 25, 1984, with the death of a nine year old girl by the name of Dawn Hamilton. The story plays out as follows: Dawn approached two boys and an adult male that were fishing at a pond in a wooded area near Golden Ring Mall in eastern Baltimore, Maryland. Dawn asked the boys to help her find her cousin, they declined the adult male however agreed to help her look. This was the last time anyone saw Hamilton alive. Hamilton’s body was found to have been raped, strangled and beaten with a rock. The police collected a boot print at the scene and DNA that was found in Hamilton’s underwear. The police also relied on the witness testimonies and line-ups, which in this case was the photo array. With the five eye witness testimonies and a tip the believed to be suspect was found. Kirk Noble Bloodsworth a prior U.S. Marine with no prior criminal record was taken into custody and charged with intentional first degree murder, sexual assault and rape. Bloodsworth was basically convicted on the eye witness testimonies. The state requested the death penalty. Bloodsworth was sentenced to two consecutive life terms. (BLOODSWORTH v. STATE, 1988)
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.
Throughout the trial, there were multiple points in which Bibbins had false accusations thrown against him from the victim and the law enforcement of Baton Rouge. The victim clearly misidentifies her rapist and clearly is distraught while identifying, "The victim's initial description of the attacker was a man with long and curly hair, wearing jeans. Bibbins was wearing grey shorts and had short, cropped hair at the time" (Innocent Project). As with false accusations there were multiple occasions in which evidence proving Bibbins innocence were not present during the trial. Baton Rouge police had discarded evidence from the crime, "The allegations of evidence tampering gained credibility in 2003 when DNA testing unavailable at the time of Bibbins' trial excluded him as the girl's rapist" (Sherrer). Eventually Bibbins is able to use this information of evidence tampering to help strengthen his case against the city of Baton
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.
A body was found with no identification was found on the body. An external examination of the body found numerous needle marks and bruising and thrombosed veins in the cubital fossae. The head showed evidence of a blunt trauma and small paint and metal fragments were removed from the wound. Analysis of the contents in the stomach found a few partially digested potato chips and some partially digested pills. A small amount of residue was extracted from the tin for analysis. Footprints were evident on the carpet where soil had been tracked in. Soil samples were collected from theses footprints. This analysis will show how Infra-red spectroscopy and Chromatography would be useful in finding both the cause of murder and possibly who the culprit was.
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

On Wednesday, November 16, 2011, Katherine Stang, Aresh Kabirnavaei, and Andrew Roller, all students in the Master’s of Forensic Science program gave thesis presentations to the Forensic Seminar Class. The following paragraphs will summarize each topic.
On that night in Brentwood, the two murders were committed by a heartless individual who had no remorse for his victims. The scene outside Nicole's apartment was gruesome to say the least. Goldman and Brown Simpson’s blood covered the once cement-colored sidewalk. The investigators found multiple pieces of evidence at the crime scene. Most of the evidence leads directly to O.J. as the perpetrator of the two murders. Detectives collected and examined hair, blood, and small fibers (Linder). Other incriminating evidence at the site included a bloody glove and multiple shoe impressions that match the ones found in O.J. Simpson’s white Ford Bronco

In crime scene investigations, hair is one of the most common types of evidence encountered. Hair evidence is picked up at the scene, and usually collected from several different areas on the body. Through hair analysis, we can determine if the source is human or animal, and what race the source is a member of. When analyzing hair, the color and structure is the main view of focus and is determined through microscopic magnification. Today hair evidence has played a significant role in criminal investigations and has helped solved many cases.
