It's late so I may not be reading all of this correctly but it appears to me that Federal Authorities do not have jurisdiction for white on white crimes committed within NA territory. However, the State of Colorado may have certain rights to prosecute such crimes.
"The single question that we do or can decide in this case is that stated in the certificate of division of opinion, namely, whether the Circuit Court of the United States for the District of Colorado has jurisdiction of the crime of murder committed by a white man upon a white man within the Ute Reservation, and within the limits of the State of Colorado; and, for the reasons above given, that question must be answered in the negative."

I don't think it would be entirely illogical to explore the potential of Dylan being taken to a reservation. The local police can't just roll right on through there looking for him. The NA would likely be the ones to do the searching or allow special permission for local LE to search. I've looked at areal maps and it looks very isolated, modest homes spread very far apart, desert/arid looking conditions. I'm sure some, maybe even most, are not living in a bubble but it is still remarkably bubble-like... IMO.
What you cited is for a
trial. Of course a white on white TRIAL will take place in a State court and not through the tribal council since it is none of their business.
The Feds can and will "roll" through there any time they want. IMO

The United States Constitution, treaties, federal statutes, executive orders, and court decisions establish and define the unique legal and political relationship that exists between the
United States and Indian tribes. Federal laws vest the Department of Justice with primary jurisdiction over most felonies that occur on Indian lands in most states. As such, the Federal Bureau of Investigation and the United States Attorneys' Offices are the primary federal law enforcement agencies responsible for
investigating and prosecuting most serious felony crimes that occur in Indian country including homicides, aggravated assaults, sex offenses, and large scale theft or embezzlement. Other federal law enforcement agencies are also active in Indian country; for example, the Drug Enforcement Administration (drug offenses), the Bureau of Alcohol, Tobacco, Firearms and Explosives (firearms offenses and arson), United States Marshals Service (fugitives and sex offender investigations), and Customs and Border Protection (border offenses). Most common less serious misdemeanor crimes are usually investigated and prosecuted by tribal law enforcement agencies. Tribal police and tribal courts handle the majority of criminal offenses occurring in Indian country and often do so in ways that are appropriate given the priorities, needs, and resources of each particular tribal community.

Protecting tribal communities is a little knownbut highly importantresponsibility of the FBI.
Weve been helping to ensure safety and security in Indian Country* since our founding in 1908. Today, more than 100 special agents from 20 different field offices investigate cases on over 200 reservations nationwide. We work closely with a range of partners, including tribal police and federal agents from the Bureau of Indian Affairs. Our exact role varies from reservation to reservation, but we are generally responsible for the most serious crimes**
such as murder, child sexual and physical abuse, violent assaults, drug trafficking, gaming violations, and public corruption matters.
Over this discussion.
