Sherry Arnold's disappearance and presumed death is now the subject of a feature article in People magazine.

The article detailing the story of the missing Sidney High School teacher was posted on the magazine's website on Friday night.

The story features a picture of Arnold and her husband Gary, and chronicles the mystery that has people in Sidney on edge.

The story details the multi-state search, and the two men being held in Williston, North Dakota waiting to be extradited to Montana to face charges of aggravated kidnapping.

The article states: "Family members have been told that one of the men has confessed to killing Arnold, but they're still desperately waiting to hear how and why."

Authorities have released little details in the investigation. They do believe Sherry Arnold is dead and have asked landowners between Sidney and Williston to look for disturbed soil on their property.

The People article notes that many people in the area have been quick to blame the crime on a regional boom in oilfield jobs that has drawn many outsiders to the region, noting that the parking lot outside the Williston, N.D., Walmart has been turned into a makeshift homeless camp of wall-to-wall trailers.

It adds that Sidney schools superintendent Dan Farr, himself a former oilfield roustabout, cautions that residents shouldn't rush to judgment against the oil workers.
