"Unsolved Mysteries" is back once again on the platform of Netflix on Oct. 19.

It came back with more chilling cases and scenarios that were said to be wilder than the first volume, according to a Women's Health Mag article.

One episode entitled "Death in Oslo" remains to be in the mind of viewers.

"Death in Oslo" follows the story of one unidentified woman who called herself "Jennifer Fairgate."

Details surrounding Jennifer Fairgate's life and death remain a mystery, even after thorough research and investigation were done for more than 25 years.

The only detail known about Jennifer Fairgate was that she checked into room 2805 of the Oslo hotel on May 31, 1995, and never checked out.

Jennifer Fairgate arrived at the Oslo Plaza, dressed all in black. She was wearing a Citizen Aqualand, model CQ-1021-50 watch, according to a report.

She was listed as 21 years old, but later reports revealed that she was around 30 years old. The investigators dubbed her as the "Plaza woman," adding that she had blue eyes and short dark hair.

She was known to weigh about 150 pounds and was 5'2". Jennifer also spoke English and German, said the hotel employees.

Reports said that Jennifer had traceable connections to Belgium. However, she gave false details to the hotel reception.

According to the details that she provided, she lived at Rue de la Stehde 148. It was found that the said address did not exist. Also, her phone number and zip code were incorrect.

"But, when the investigators went through the room, they couldn't find any identity. No credit card, no driver's license, no wallet, no car keys, no home door keys, which people normally bring with them," a statement said in the Women's Health Mag report.

On June 26, 1996, she was found buried in an anonymous grave after police spent a year identifying her.

What Happened?

Jennifer Fairgate was reportedly last seen alive on June 2, 1995 at 8:06 p.m. She ordered her dinner but did not eat any until Saturday, according to the pathologist who did the autopsy.

She was discovered shot to death 45 minutes later by police, and most accounts point to the incident as a suicide.

The crime scene report said that all of the documents said it is 99.9 percent sure it is suicide. However, some details suggested otherwise.

There was no passport, and an official said it is a very rare occurrence as many people need to have a passport to come to Norway. The serial number of her gun was also removed professionally by acid.

The National Criminal Investigation Service traced it to Belgium. The gun was also found in her right hand. Comparing to the position of her cutlery, it made investigators wonder if she was left-handed.

Investigators also found that all the labels on all her clothes were removed. All of her belongings were also destroyed or sold at police auction not long after her funeral, which leaves investigators with few leads to follow.
