Where is this in the Constitution?

Historically, the Constitution didn't give the feds "police powers." Ergo, from a strict constructionist Constitutional perspective, murder and other intrastate acts are left to the state to regulate vel non.

Stated differently, in contrast to the majority opinion in Roe v. Wade, the federal government has no authority to legislate in this area. It's the exclusive jurisdiction of the states - much like marijuana. See, for example, the dissenting opinion in Gonzales v. Raich.
