This Is My CSI Homework! It Is About Lots Of Things:

Fingerprints
Blood Types
DNA Fingerprints
Chromatography
Microscopes
A Case Sudy On A Particular Case & How It Was Solved

Fingerprints

2008-11-30T11:04:00.000-08:00

Fingerprint identification, or palmprint identification is the process of comparing questioned and known friction skin ridge impressions from fingers or palms to determine if the impressions are from the same finger or palm. The flexibility of friction ridge skin means that no two finger or palm prints are ever exactly alike (never identical in every detail), even two impressions recorded immediately after each other. Fingerprint identification occurs when an expert determines that two friction ridge impressions originated from the same finger or palm. This is useful as a fingerprint may have been taken from a weapon and they could match it up to a fingerprint from a suspect.

Blood Types

A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells. These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system, and some of these antigens are also present on the surface of other types of cells or various tissues.

DNA Fingerprinting

2008-11-30T10:02:00.000-08:00

The chemical structure of everyone's DNA is the same. The only difference between people (or any animal) is the order of the base pairs. There are so many millions of base pairs in each person's DNA that every person has a different sequence. Using these sequences, every person could be identified by the sequence of their base pairs. However, because there are so many millions of base pairs, the task would be very time-consuming. Instead, scientists are able to use a shorter method, because of repeating patterns in DNA. These patterns do not, however, give an individual "fingerprint," but they are able to determine whether two DNA samples are from the same person, related people, or non-related people. Scientists use a small number of sequences of DNA that are known to vary among individuals a great deal, and analyze those to get a certain probability of a match.

Chromatography

Chromatograghy is the proper term for seperating substances to find out the different materials in it. There are lots of methods of chromatography.

Microscopes

2008-11-30T09:20:00.000-08:00

A microscope is an instument for seeing objects too small for the naked or unaided eye to see. The microscope is used to trace DNA off things eg.clothing, to match it to other DNA particles.

Case Study

I'm Studying The Case Of . . . . . Daniel Gonzalez,

Also Known As 'Freddy Kruger'

Wanting the fame and place in criminal history, Britian's Daniel Gonzalez became one of Britains most dangerous serial killers. In 3 days Gonzalez murdered 4 people, to then be told he was to spent the rest of his days behind bars.

Living with his mother, at the age of 26 he tried to escape his boredom by playing on playstation games and watching horror movies such as 'Freddy Kruger' and 'Jason, The Friday The 13th Killer'. At the age of 24 he began fantasising about killing people like his heroes on the horror movies. Later he then told the police he had 'wondered what it would be like to be Freddy Kruger for the day.'

Gonzalez was not mentally ill but even as a small child his bevavior worried his parents, so at the age of 10 they took him to see a psychologist. He had started talking to himself and laughing for no reason, and had been thown out of school for putting drawing pins on a chair. He was repeatedly admitted into hospital for psychiatric treatment and in 1999 was diagnosed as being schizophrenic. In 2003-2004 docters decided Gonzalez was not metally ill or a high risk. The were proved wrong as later in the year on the morning of Wednesday 15th September when the attacks began.

At around 9am that Wednesday he took a steak knife from the kitchen drawer. packed a rucksack with clothes and took a train from Woking to Portsmouth, Hampshire. Two hours later he got off at Hillsea station after spotting the isolated Portscreek area, a favourate spot for walkers and joggers. He then approached Mr King, 61, and his wife Janice who were walking their dog. Gonzalez hid the knife against his thigh then lunged at Mr King shouting "I'm gonna kill you!", Mr King later said "I thought he was going to kill me, I was really scared, the knife truck my chin several times and at 1 point I saw it under my chin close to my throat!" The two men then tumbled into the undergrowth and stugled for about 30 seconds before Mr King managed to push Gonzalez off him. He then ran off muttering 'Sorry, I'm a schizophrenic, I can't help it.'.

Fustrated by the failure of his first attack Gonzalez then took a train to Worthing, West Sussex, determind to find someone more vunerable. Arming himself with a second knife and a white hockey mask he lay in some bushes waiting for his target. Attacked by him from behind pensioner Marie Harding, 73, was on her way home. Gonzalez stabbed her in the back then slit her throat before rummaging through her purse for £20 as she bled to death. On the train nheading back home he occupied himself by writing up a diary of his first killing.

The next day he set off to Central London in his bid to commit up to 10 murders. After stealing another two knives he got a night bus to Tottenham, North London at 4am on Friday 17th September. Walking the deserted streets her spotted pub landlord Kevin Malloy, 46, walking home alone. Gonalez later laghed as he revealed to police that he was "just some bloke walking down the street and I pulled out the knife and stabbd him." Mr Malloy was discovered an hour later with stab wounds to the face, chest, neck and abdomen.

Gonzalez then switched his focus to people in their own homes- possibly because he had run out of knifes after dumping the last 2 in a park. At 7am he broke into the terraced home of Koumis Constantinou, 59, and his wife Christella in Frobisher Road, Hornsey. The couple were woken by the sound of glass breaking and ran out to find Gonzalez emerging from the kitchen with a 8 inch knife. Mr Constantinou grabbed a cradle to defenthimself but the didn't stop the psychopath from plunging a knife into his arm and chest. Dropping the cradle Gonzalez tried to stab him again, Mr Constantinou managed to grab his hand before he stabbed him, causing Gonzalez to bite him so he bit his neck. Mr Constantinou's wife then ran out of the house to scream for help. Gonzalez then fled and took a taxi to Highgate, North London. With blood splattered clothes he still managed to buy a knife for his final and most savage attack.

Derek Robinson, a 75 year-old retired paediatrician, and his wife Jean, a 60 year-old music teacher, were having breakfast when Gonzalez rang their front door buzzer at 24 Makepeace Avenue, Highgate Hill. Gonzalez stabbed them both repeatedly in the head, face, neck and chest in the hallway of their own home. He later revealed that he acctually stood there and took a breather before stabbing them. The male was stabbed a few times in the throat and the woman was stabbed in the throat and the chest around were the heart was. Minutes later a decorator arrived to find blood splattered across the walls. Gonzalez who was interupted as he prepared to take a shower, told him, "Sorry about this mate." then fled from a window.

He was caught after police followed him onto a train at Tottenham Court Road underground station. He was then sentenced to 6 life sentances. His last victim was himself as he used the shattered edges of a CD case to slash his wrists and then gradually bled to death.

Timeline Of Who Gonzalez Killed

Evidence

The court was told on Wednesday that following his arrest in September 2004, a note written by Gonzalez was discovered among property he left at the luggage deposit at King's Cross Station in London.
The note read: "I will be a serial killer. I am gonna make sure I get to London and kill some old bill as soon as I can...
"I will kill as many old bill as I can as best I can.
