Hard Evidence: Can't collect blood

[Svengali]

Hi!

I'm not able to collect any of the blood stains in front
of the door at the crime scene in case #2.
I use the LVC and then I cannot select any tool (swab
or others) to take a sample :(

Any help?

Ugh... solved. Hat do apply litres of LVC to be able to collect that... bood stains have been pink already, but no "swoosh-there's-evidence" sound was heard...
