Evidence collection

There are many types of evidence in a crime scene. 


The first one is called trace evidence, it contains:

dirt,soil,twigs,fibers,sand,grass,leaves,

tape,gravel and bullet fragments.

When the proof is identified you should collect it and follow the steps below:

1.Take a photo of it and document it

2.Secure the data(place it somewhere safe fe.in an envelope or in a bag)

3.Close,seal or tape a paperbag/envelope and label it.

4.Put a date,signature and time on the package.


The second type is biological evidence.

It includes skin,blood,semen,hair,urine and saliva.Swabs can include fe.bitemarks,nails,buccal or skin.

Hair should be placed in a wrapping.

The same process for packaging,securing and labeling is used for the collection of trace evidence.


The third type is clothing evidence.

If the person is wearing the clothes they had at the time of the crime,all items can be considered as evidence.

If the person is not wearing clothes they had on during the assault,clean clothes put on later - fe. underwear may still contain bodily fluids other than the patient’s.All stains or tears must be documented,clothes must be placed in separate bags.

Reindeer eyes change color in different seasons

Reindeers have the ability to change the color of their eyes to help them get through dark, northern winters. Glen Jeffery - professor of neuroscience at the Institute of Opthamology at UCL- explains why most of the time we see glowing, golden eyes of animals. Tapetum lucidum is a part of an eye which produces that golden reflection and thanks to it they have better sight in the dark by bouncing light from the back of the eye through the retina a second time. Everything changed when the slaughterhouse in Norway sent Jeffery two jars - the first one from winter and the second one from summer - filled with reindeer eyes.He was shocked when he opened the winter ones because the eyes were blue. He discovered that it’s a miraculous bit of evolution that gave this animals the most intriguing eyes in the world. source:theconversation.com
