This case happened in a federal park in the national parks system, which makes it exclusive federal jurisdiction-according to precedent for criminal juris diction. But again- even that has been argued the other way.
so there has been some debate on this with arguments on both sides. That link is a good primer on the issue…gives an expansive reading argument (over current case law).
Again you're wrong. The crime has nothing to do with the jurisdiction, it's the status of the land that determines jurisdiction. The federal government cannot assert exclusive jurisdiction and stop a case from being filed in state courts if the state has jurisdiction, or vice versa.
That primer is ok, I read it before you posted it because I don't work for the NPS and I wasn't sure that NPS had proprietary and concurrent lands, though I suspected they did.
I'd suggest you look at the DOJ's criminal resource manual, which
explains exclusive and concurrent jurisdiction in simple terms.
"There are three methods by which the United States obtains exclusive or concurrent jurisdiction over federal lands in a state: (1) a state statute consenting to the purchase of land by the United States for the purposes enumerated in Article 1, Section 8, Clause 1 7, of the Constitution of the United States; (2) a state cession statute; and (3) a reservation of federal jurisdiction upon the admission of a state into the Union.
See Collins v. Yosemite Park Co., 304 U.S. 518 (1938). Since February 1, 1940, the United States acquires no jurisdiction over federal lands in a state until the head or other authorized officer of the department or agency which has custody of the lands formally accepts the jurisdiction offered by state law.
See 40 U.S.C. § 255;
Adams v. United States, 319 U.S. 312 (1943). Prior to February 1, 1940, acceptance of jurisdiction had been presumed in the absence of evidence of a contrary intent on the part of the acquiring agency or Congress.
See Silas Mason Co., Inc. v. Tax Commission, 302 U.S. 186 (1937). See also
JM 9-20.000 et seq., for a discussion of federal enclave jurisdiction."
Also, see:
664. Territorial Jurisdiction
and
Glacier NP: Final Master Plan (Appendix B) (which appears to show that most of the park is in the exclusive jurisdiction of the United States, but parts of the park retain the state's concurrent jurisdiction).
Lastly,
http://npshistory.com/publications/fletc/law-enforcement-jurisdiction.pdf though I would put as much stock in a memo from the 1970's being current and controlling as I would a summary of case law from 1967.
