TRACE EVIDENCE
JONATHAN BLACK
2.
Untitled Slide
I believe this to be a lock box key.
To learn more about this, I would contact a locksmith.
This could potentially be very valuable evidence as a locksmith might be able to tell you what banks use this type of key.
Type of key. This means that you might be able to link it to someone's lockbox, giving you a name.
3.
Untitled Slide
To me, this appears to be sand.
To find out more about this, you would see a geologist, who might be able to ID it.
This might link it to a specific area, which is useful because it can tell you where
your victim has been, or that it came from someone else who went in that sand. This is weak evidence however,
because while it can link someone to the scene, a lot of people might have walked through this sand.
4.
Untitled Slide
This appears to be a twisty tie, like those on bread bags.
To find out more about this, I would ask any nearby factories that make them who they sell them to.
After this, you could check the employees for a connection, and then check the stores that the ties were sold to
to see who bought them.
This isn't all that useful however, as a lot of people buy packaged items. At most it further indicates someone.
5.
Untitled Slide
This appears to be gum
To find out more, I'd take it to the lab for DNA analysis, as there's no way chewed gum doesn't have DNA.
This is very, very useful because it can give you a DNA profile from the scene to compare to any suspects.
If there aren't any matches it becomes less useful, as you'll have to travel up the supply chain and check
employees involved in its manufacture and anyone who bought it.
6.
Untitled Slide
This appears to be a piece of colored pencil tip.
To find out more about this, I would take it to the lab to have it identified.
After that, I'd take it to the factory that produces it and figure out where they sell it to.
I'd then check employees of the factory for connections to the Vic, and then see what connection buyers might
have to the retail store. This is a little useful, but at most it could only weakly link a suspect to the scene.
7.
Untitled Slide
To find out more about this copper wire, I would visit suppliers of this and figure out who their customers are.
After this, I would check to see which of the companies who bought it were in or near the area.
After that, I would check to see what connection the employees of companies with work nearby exists w/ Vic.
This is useful because copper wire is semi-rare, meaning there's little reason it would be at the scene except
that one of the employees of the companies (particularly electrician or construction) was near the victim.
8.
Untitled Slide
This appears to be a nail with dirt trapped under it.
Assuming you can't get DNA from the nail, the next best thing to do word be to visit a geologist.
The geologist might be able to ID the dirt under the nail and link it to a particular area.
This could tell you what area to search for suspects in, or link an existing one who's been there to the crime.
This isn't super useful, as there's a chance that many people walked through an area containing this dirt.
9.
Untitled Slide
This appears, to me, to be a blonde hair.
Since this is trace evidence, it's safe to assumes that it has no follicle.
To learn more about its would take it to a mDNA analysis specialist for processing.
While this won't give us an exact genetic match, it will enable us to strongly link a suspect to it.
This is useful, but since mDNA is inherited from the mother, it complicates matters if other family is suspected.
10.
Untitled Slide
This appears to be a burned and carved piece of bone.
I would take it to an Orthopedic Specialist for ID, then any artisans who work with those bones.
After that you could identify where the bone came from and who bought whatever this came from.
This seems like it would be a very useful piece of evidence, as bone jewelry doesn't seem common.
It could also link someone you already suspect to the crime scene further.
11.
Untitled Slide
This is a used match.
I believe that the best thing to do would be to take this to the lab to have it checked for accelerants.
If you find any, you could check stores in the area to see who bought it, changing your pool of suspects.
If there wasn't any, then you might find something, maybe tobacco residue, that links to a brand, and a buyer.
The main problem with this is that matches are mass produced, very commonplace, and this is heavily burned.
12.
Untitled Slide
This appears to be a peach pit.
The first thing I'd do would be to take it to the lab for DNA analysis, as it likely has some on it from being bit.
The second thing I'd do would be to take it to a fruit market and determine what type of peach it came from.
This would enable me to figure out what markets sell this peach, and get a list of buyers, aka SUSPECTS.
This isn't very useful without DNA on it; there's many reasons it could be at the scene, and many who buy 'em.
13.
IM BRUCEMAN, I MEAN BAT WAYNE... ****
This appears to be residue from a red velvet cupcake/cake.
The first thing to do would be to take it to the lab to confirm its diabolical origins in the underground bakery.
After that, I would have to go on a hunt through local branches of this nefarious ring and crack some heads.
This will eventually give me list of recent buyers, and vengeance for the cake bosses' murder of my parents.
This list could then be compared to my punching bags- err, suspects, and maybe confirm who was there.
14.
This is a wood shaving. Im a detective, not a lumber jack.
This appears to be a sliver of wood.
The first thing to do would be to take it to the lab and determine what kind of wood.
After that, I would visit local distributors of this and see if any of their customers matched my suspects.
This is some pretty unreliable evidence though, as there's a number of ways it could be on scene, and
a large number of sources for this wood chip asides from suppliers, like the forest.
15.
I HAVE NO IDEA WHAT THIS IS. ALSO, INDIANA JONES IA A BOSS.
Hmm, yes, this appears to be an early -16th millennium Ethiopian nose picker.
The best thing to do here is to take it to a museum or eccentric college professor for identification.
The next best thing to do is determine who would be interested in this priceless object. Perhaps ex-nazis.
Out of the list of private collectors who would likely be interested, I could check to see which knew my victim.
However, despite perhaps gaining a new group of suspects to consider, I don't see this as being any help.
16.
Untitled Slide
This is a button.
A BUTTON
A clear, plastic, thread-less button
No self respecting investigator would use this as a basis for an arrest. Quickly, arrest all the seamstresses!
Short of it having DNA, or a suspect missing a button like it on a shirt, this is no help. At all. It's too common.
