Kristi Noem is blatantly lying.
Like you wrote, jurisdiction and non-cooperation are two separate matters.
On 22 Nov 1963, the (federal) USSS prevented (local) Dallas PD from conducting a lawful murder investigation into the death of JFK by moving his body and removing evidence.
Non-cooperation.
But the Dallas County District Attorney had already taken independent action by convening a Grand Jury.

"In November 1963, following the assassination of President John F. Kennedy on 22 November 1963, Lee Harvey Oswald was arrested and charged with the murder. The Dallas County Grand Jury played a key role in the legal process related to this case. Specifically, the Grand Jury of Dallas County, Texas, was active during this period and was involved in indicting Jack Ruby on 26 November 1963, for the murder of Lee Harvey Oswald, who had been killed by Ruby two days after Kennedy's assassination."

The Hennepin County DA should have already convened a Grand Jury seeking a "True Bill" for the charge of Second Degree Murder against Jonathan Ross for killing Renee Nicole Good.
The Minnesota Bureau of Criminal Apprehension (BCA) will obtain a search and arrest warrant for Jonathan Ross from a state judge after the indictment is unsealed.
An accusation or indictment is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
