In 1983 a young 11-year-old girl, Sabrina Buie, was found in a soybean field in a rural area of Red Springs, NC. She had been raped and murdered. There was no physical evidence as to who committed the crime. However, suspicion was cast upon two half-brothers, Henry Lee McCollum, 19, and Leon Brown, 15, who had recently moved to the area from New Jersey and were considered outsiders. Both men were considered mentally disabled. The brothers were arrested. After many long hours of threats and questioning, McCollum broke down and admitted to a story that he made up so the questioning would end. He thought he would then be able to go home. Afterwards, Mr. Brown was told of the confession and that he would be executed if he didn’t cooperate. They both signed the coerced confessions. The men were tried in court and found guilty though they both stated the confessions were coerced and they were not guilty. Both were found guilty and given the death penalty. In an appeal, the death penalty was upheld for Mr. McCollum, but Mr. Brown’s sentence was changed to life in prison.
Upon entering the room where anna had died beside the body the blood The blood is the is the second thing to stand out.the blood recovered scene of the crime belonged to Anna or Erica Piedmont (suspect). After further investigations we found that the blood had belonged
Were each of the two men involved in the crime mentally unstable? Could this have been a factor as to why the crime was committed?
In 1984 Dr. Alex Jeffreys came up with deoxyribonucleic acid (DNA) fingerprinting, which is also known as DNA profiling or DNA typing. DNA fingerprinting is the analyzing
A positive aspect of this is that forensic scientists only need a small amount of a sample to get the results they need (“Forensic Science” 12). These samples can come from many other forms of identification other than fingerprints and bloodstains. A few moderate examples include strands of hair, tiny beads of sweat, and a saliva specimen (“Forensic Science” 12). Forensic Science Technicians stated that “crime scene investigators may use tweezers, black lights, and specialized kits to identify and collect evidence.” They also stated that examining autopsies prove to be beneficial in a crime investigation (“Forensic Science Technicians”
There comes a time in the criminal justice system where a law that was written to protect us will be challenged through a court case. That case will eventually make history and will become a reference in future cases with similar dilemmas. In 1983, one particular case met the criteria (Arizona vs. Youngblood). In this case, Larry Youngblood was convicted by a jury in Arizona of child molestation, sexual assault, and kidnapping of a ten-year-old boy. Both a criminologist for the State and an expert witness for the defendant testified as to what they believed the results were from the tests that were performed on the samples shortly after they were collected, they also commented on later tests performed on the samples from the boy’s clothing
This is a criminal case, in which the Supreme Court ruled that there was no probable cause to arrest Hayes. Hayes did not give consent to be taken to the police station and be detained plus fingerprint. Therefore, Hayed Fourth Amendment rights were violated and the conviction was overturned.
Hello ladies and gentlemen, my name is Sandy Doan. I am a hair analysis expert. I work in the lab of California’s Police Department. I work using the Scanning Electron Microscope, also known as SEM, for analyzing different types of small evidence. I have been spent 8 years on this job which why I am wearing glasses due to the constant straining over the years. However, today I am here to determine whether or not the three suspects are responsible for the murder that has been committed. Using the lab results about the hairs, I am going to explain how to find the suspect with the hair analysis that we have collected.
DNA has become a vital part of criminal investigations. DNA can include and exclude suspects of criminal investigations. During a criminal investigation, all DNA should be collected, properly preserved and tested, but at times this does not occur or the technology was not available for this process to occur. In addition, DNA has become an imperative portion of exoneration cases.
In this paper I will be comparing contrasting two various aspects of forensic sciences used, and talking about the different tactics used to identify suspects; as well as the contrasts between the two methods. The man I will be talking about is John Wayne Gacy. The two methods I will be going over are, Finger print DNA and Forensic toxicology. These two are very similar, but made substantial differences in the evidence in his case.
What influence does the height at which simulated blood is dropped have on the size of the blood spatter?
I observed passive bloodstain patterns- from the wire put on Jessica’s wrist, and blood due to the sexual assault. First I photographed the bloodstains and bodily fluid stains (semen) on the mattress in Couey’s room. I took photos with measurements as well. The width and length of pattern was documented along with the time. Photography, measurements, and reconstruction of bloodstain all complete. I then took samples of the blood for DNA analysis. It was determined later that the blood was Jessica’s bloodstains and the semen belonged to sex offender Couey due to the sexual assault he committed to 9yr.old Jessica.
On 10/25/15 I arrived at 6011 Jacksonville-Conway Road in reference to a possible shooting call. Upon arrival I made contact with Margaret Davis, who advised that on this date her ex-husband, Jerry Davis, shot himself at his residence. I observed Mr. Davis in a medical bed in the living room of his residence with a small caliber handgun in his right hand and laying on his chest. I also observed a spent .22 Long Rifle cartridge laying on Mr. Davis' shirt next to his right hand. Mr. Davis did not have any immediately observable wounds but he did have a small area of blood coming from around his mouth and was obviously deceased. Sgt. Bowden was notified of the incident. MEMS unit #619 responded to check for signs of life on Mr. Davis and medical instruments indicated a shallow arrhythmia. MEMS began CPR on Mr. Davis and
On 6/19/16 at 2341 hours my partner, Officer Acosta #0044, and I were working patrol assigned to unit 3A22. We responded to a radio call of “shots fired” in the area of 101 W. Washington Bl.
