Man charged in stalking, assault in Yellowstone

JACKSON (WNE) — A Utah man is facing federal charges after allegedly traveling to Yellowstone National Park with the intent to kill a person and fleeing rangers in a high-speed chase that ended with his arrest in Grand Teton National Park.

Jose Bradley Isaacson, of Logan, Utah, was charged on June 23 with interstate stalking and simple assault in a case federal investigators said involved threats to life, emotional abuse and an attempt to evade law enforcement.

According to court records, Isaacson sent threatening messages to the victim and claimed he had access to a gun. He also threatened the victim’s family members. 

According to court records, the victim said Isaacson demanded money during the days leading up to the assault. The victim transferred a total of $2,500 under what the affidavit describes as “emotional pressure and threats.”

The victim, a Yellowstone employee, reported the threats to park rangers on June 19. 

By the evening of June 21, Isaacson had allegedly arrived in the park to confront the victim, whom he allegedly assaulted during a struggle. He then fled, taking the victim’s phone with him.

Around 5 a.m. June 22, Isaacson allegedly stole a running rental car from the Old Faithful Inn parking lot and fled south into Grand Teton National Park.

According to court filings, he “drove at speeds up to 100 miles per hour” before rangers in Grand Teton National Park deployed spike strips to disable the vehicle. If convicted, Isaacson faces up to five years in prison and a $250,000 fine for interstate stalking.

The U.S. Attorney’s Office has requested detention pending trial, citing the nature of the charges and ongoing public safety concerns. No bond had been set as of Friday.
