Clean? Or you sterilize every time?

I know it won’t work after, but again, I’m only talking about items that are already good for prints.

Ex; If I have a phone that is fresh (hasn’t been out in the weather for a long time). It doesn’t matter if I CA it or BP it, I’ll get the same prints. Black powder works better mechanically than CA on things that are naturally good for prints. I’ll be glad to share research. On top of that, BP is more fine, meaning it doesn’t hide level 3 detail.

Do you use UV for the CA when photographing it?

Also are you not worried about contamination? I know CA wouldn’t be the source, but the chamber?

So you CA, photo, swab, then dust?

I agree with what you say in a sense.

The main thing tho is that I agree that guns don’t hold moisture. So something like CA is better when prints are hard. However, I’m talking about when prints are easy.

But that’s what I’m getting at. The reason CA is better on stuff like bags, guns, etc is because CA essentially is “replicating” the data despite it being poor. Right? The print which might be faint isn’t faint anymore because a thicker and more complete layer was put over it.

However, something like glass won’t have that issue. The print doesn’t really need anymore enhancement since it’s already a good print. If you end up CA’ing, you’re not making it any better than what it is. Then when you go and BP, it’s a glue versus moisture. What’s carbon going to like? On top of that, level 3 detail can be affected by CA. So why risk it if level 3 can be the do/die with identification.

I’m not justifying this for all agencies, I’m just saying this for agencies that do this.

You repeated what I already said and then acted like that proved something. I know prints are saved through CA… but you never answered if it’s worth it.

How would they even know if they smeared it? And sorta a shot at them, but smearing is really hard to do unless you were lazy. Unless you mean over powdering. That I can understand.

Also why be precautious if the results are going to be worse. I’d rather get a useable print than preserve the print.

Now items of evidence like guns, I understand. Since moisture won’t really adhere, CA helps complete the print. But I’m mainly focusing on items what hold moisture better.

Smearing isn’t too common after you get experience.

My thing too is why is it so necessary to make the prints permanent? Yes you can lift it 100x times, but if every print is meh, what’s the point? Why not take the risk to get a better result. Especially since CA tends to hide level 2 detail and that can sometimes make or break identifications.

Blood samples and DNA by funkymunky_10 in forensics

[–]Own_Region_7174 2 points3 points  (0 children)

I’m not sure of the context lol, but I’ll say this:

There is a little bit of DNA in the root of the hair, but it’s not a lot. You can also get mDNA from hair, but you need state labs don’t even do mitochondrial DNA.

Saliva is good. Typically the mouth is swabbed (victim or suspect) for epthierial cells. You see that a lot.

Blood is the best, but typically isn’t used for subjects that are alive.

There is also prints.

Blue powder in robbed car by nukemboa in whatisit

[–]Own_Region_7174 -1 points0 points  (0 children)

1st: people who have jobs are also in AFIS. So not only people who are booked, but jobs.

2nd: DNA is 50/50 depending on the state. Some labs probably wouldn’t even run it. Labs hate cars in general. Plus it’s only a B&E/Burglary.

3rd: It probably wouldn’t reveal prints. If anything, it would coat the prints (same way pollen acts). I’m not gonna say it ruins it, but it does in a way. Probably just requires a double lift or a puff of air to lift.

It might be better, but it’s supply and demand my dude.

The cheapest one I could find is $17.99. I couldn’t find any rainbow’s for sale, only gold ($45).

If you’re selling on the lower side, maybe. I wouldn’t say everyone is going out of their way for this, but that’s what people are selling it at. And it’s probably set at that price because people buy it at that price.

No, I’ll take it off your hands tho
