The expression in cold blood refers to homicide, or murder. Specifically, it speaks to intent or premeditation. It didn't just occur in the heat of an argument or by accident. It also hints to the emotional view that blood and having a heart has an emotional meaning. If you are "warm" blooded and "have a (nice) heart", you would never commit murder.

The man killed his father in cold blood.


The man was called a cold-blooded murderer.
