Yellowstone National Park recently announced that one of its tourists was sentenced to one week in jail after trespassing into a "dangerous" geothermal area.

The national park, which is mostly located in Wyoming, shared a Department of Justice (DOJ) press release about the sentencing on June 13. Lynwood, Washington, resident Viktor Pyshniuk was handed a seven-day jail sentence over the trespassing incident.

Officials say the 21-year-old man wandered away from the boardwalk area at Steamboat Geyser in Yellowstone's Norris Geyser Basin during his visit. According to the DOJ, the Steamboat Geyser is the world’s tallest active geyser and is "the most dangerous" geyser in the world.

"It has erratic and unpredictable eruptions that can rise anywhere from six to 300 feet high," officials said.

According to the DOJ, a National Park Service (NPS) employee had reported seeing someone "walking off the boardwalk" near the geyser. Pyshniuk reportedly told the NPS officer that he was trying to get pictures of the hot spring.

"The employee had taken a photo of the defendant who had clearly crossed over the fence and was walking up the hillside within 15-20 feet of Steamboat Geyser’s steam vent," the DOJ explained. "When contacted, Pyshniuk told the officer he left the boardwalk to take photos."

"While speaking with Pyshniuk, the officer showed him the signs posted throughout the area stating it is illegal to leave the boardwalk and explained that walking in a thermal area is very dangerous due to possible weak ground layer, the geothermal features of mud pots, heated steam and water, and all other dangers associated with walking in a heated, unpredictable geothermal area."

In addition to his jail sentence, Pyshniuk was also ordered to pay $1,550 in fines and has been placed on two years of unsupervised release. The man is also banned from Yellowstone National Park for two years.

Magistrate Judge Stephanie A. Hambrick designed the sentence to "deter [Pyshniuk], specifically, but also the public from leaving the boardwalk in this area."

"She expressed her concern that the defendant’s actions were seen by the people around him, and they might have thought it was okay to do the same thing," the DOJ said. "And if every visitor to [Yellowstone] disobeyed the rules, the park would be destroyed, and no-one would be able to enjoy it."

Acting United States Attorney Eric Heimann said in a statement that trespassing into thermal areas of Yellowstone is "dangerous and harms the natural resource."

"In cases like this one where we have strong evidence showing a person has willfully disregarded signs and entered a closed, thermal area, federal prosecutors will seek significant penalties, including jail time," Heimann said.

A family of four that went missing last week, including two kids ages 5 and 6, is feared dead after law enforcement officials searched a property in Hudson, Florida, and found human remains, authorities said.

The Pasco County Sheriff’s Office said the owner of the property, 25-year-old Rory Atwood, has been charged with first-degree murder.

Sheriff Chris Nocco said during a press conference on Saturday that the human remains found on Atwood’s property have not yet been identified, though investigators believe they could be those of the missing family. For now, the sheriff’s office is referring to the remains as belonging to John Doe.

Investigators said 26-year-old Rain Mancini, 25-year-old Phillip Zilliot II, 6-year-old Karma Zilliot and 5-year-old Phillip Zilliot III were last seen at about 12:30 a.m. on June 12 near Nottingham Trail in Hudson.

Authorities said that at about 11:30 p.m. on Wednesday, Mancini got picked up at her mother’s house by a friend who drove her to Atwood’s home on Nottingham Trail.

Nocco said that was the last time Mancini’s mother saw her daughter.

Mancini, her friend, Zilliot II, and Atwood were at the house with Mancini and Zilliot’s two children and Atwood’s daughter, officials said. During that time, the sheriff said, the adults were drinking.

Zilliot II and his mother spoke over the phone at around midnight that night.

"Per Rain's friend, Rain, Phillip and Rory were all drinking alcohol, and they started arguing," Nocco said. Investigators are still working to piece together what happened that night, but at about 2 a.m., Atwood allegedly frantically called a friend to say he had shot someone.

It took at least 12 hours for someone to contact the sheriff’s office, Nocco said, and by then, the information coming in was third- or fourth-hand.

On Thursday evening, deputies searched Atwood’s property with his permission. The property is about 10 acres of rural land, and authorities were unable to find anything out of the ordinary.

On Wednesday evening, investigators spoke with Mancini’s mother, who said she did not know where her daughter was and had not spoken with her since Wednesday.

Deputies returned to Atwood’s property on Friday night to search for the now-missing family, and human remains were discovered.

"This along with several admissions is what led to Rory Atwood being charged with first-degree homicide," Nocco said.

Until the remains are identified, the missing-persons case remains active.

The sheriff’s office told Fox News Digital on Sunday that the investigation is ongoing and there was no new information to provide in terms of the identity of the remains.
