Will modern DNA tests work on anything produced by the body? Saliva, sweat, tears, etc.?

Yes, so the police are going to find you. Better to turn yourself in now. ;-)

Deoxyrhibose Nucleic Acid is found in the cells of the body, like blood cells, skin, hair, etc. The composition of sweat is water, salts and urea. So no chance of finding DNA there. However, if the body sheds some of its epithelial cells along with the saliva, sweat, etc. then these can be picked up for DNA tests I presume.

Yes for saliva and sweat. Possibly for tears.

no cannot be performed on sweat or any excrement.
It has to be body tissue, from blood, bone, flesh, or skin, or even hair and nails,
