Yes, blood contains DNA, but it doesn't contain someone's name. You need to compare the unknown sample (found at the scene) to the known sample (taken from someone).

Fran—

DNA profiles can be extracted from the blood samples. DNA databases can be checked for a suspect.

You can read many articles regarding DNA on the Crime Scene Investigator Network at: Articles:DNA.

You can also read many articles regarding bloodstain on the Crime Scene Investigator Network at: Articles:Bloodstain.
