This statement (consisting of ... pages) each is true to the best of my knowledge
and belief, and I make it knowing that, if it is tendered in evidence, I shall be liable
to prosecution if I have wilfully stated anything in it which I know to be false, or do
not believe to be true.
I have been a forensic scientist since 2017. I hold a bachelor’s degree with honours in forensic science
and criminal investigation. Throughout my employment within the forensics analysis unit, I have
examined the evidence in types involves in this case on numerous occasions.
My opinion and statement will be bases on my gained experience from becoming a forensics scientist.
I have undergone the relevant and necessary training as well as the competency assessments and I
have also reported on many cases, all of which have been reviewed and the conclusions agreed by
other scientists.
I, personally, am an expert in the scientific field of forensics matters addressed in this
statement and I have been requested to provide a statement in relation to the evidential
exhibits I have examined in this case.
I have been asked on behalf of the Metropolitan Police to examine a number of exhibits
recovered from the crime scene as shown in the table below. It is my intention to prove or
disprove the facts at issue in this case and link the suspects to the scene or victim or other
areas relevant to the investigation team.
There are no conflicts in this case as I am not linked to the matter in anyway nor do I know
any of the individuals who may be linked to the case.
On the 17th of July at 18:42pm the police were called to East Surrey College where a female
body was found in a wooded area outside a building used by students. The body was found
covered in mud and the female body had suffered multiple wounds to the body and head. The
scene was preserved, and a full examination took place at the scene, resulting in multiple
exhibits were seized. A scientist attended the scene to help assist the investigation team with
recovering these exhibits. The senior investigating officer has submitted the exhibits shown
to the forensic science service for further analysis to help with the investigation.
, I have been informed that all exhibits were preserved at the scene with a documented audit
trail as to their integrity and that there are no contamination problems present.

Biological
Blood
Blood is considered a tissue; this is since it is composed of a make-up of similar
specialised cells that have specific functions. Blood is also a fluid as the
specialised cells are suspended in the plasma. Blood moves around the body
through blood vessels and is pushed by the action of the heart pumping, it
transports nutrients and oxygen to the body cells and also carries carbon dioxide
away from respiring cells in order to maintain the function of homeostasis. In the
human body there is around 4.5-6 litres of blood which is made up of different
types of blood cells and plasma. The different types of blood cells include red
blood cells which make up around 45% of blood, white blood cells and platelets
make up around 1% of blood and plasma which therefore makes up around 55% of
blood. The most common type of blood cells are red blood cells also known as
erythrocytes, they contain protein called haemoglobin and are also combined with
oxygen to make oxyhaemoglobin and to deliver oxygen to the body. Red blood
cells have a biconcave shape to increase the surface area, they are a specialised cell
that contain no nucleus to make more room for haemoglobin. (Conley, 2020)
Determining someone’s blood group
The red blood cells membrane have antigens which act to stimulate an immune
response within The antigens tell us the specific blood type which determines the
