German supermarket billionaire who disappeared hiking on the Matterhorn and was declared dead is 'living with his mistress in Moscow'

Karl-Erivan Haub, a German-American billionaire businessman, went missing while hiking near the Matterhorn mountain in Zermatt, Switzerland, on April 10, 2018. Haub, who was 58 years old at the time, was an experienced mountaineer and had been living in Switzerland since the late 1990s. He was also an avid skier and had been preparing for an upcoming ski mountaineering race.

Haub's disappearance raised concerns among authorities and his family. A large search and rescue operation was launched involving over 100 volunteers and mountain rescue teams from Switzerland, Germany, and Austria. The search focused on the area around the Matterhorn, which is known for its challenging terrain and unpredictable weather conditions.

Despite extensive efforts, Haub was not found. In July 2018, Swiss authorities declared him dead based on the assumption that he had likely fallen into a crevasse or been swept away by an avalanche. The exact cause of his disappearance remains unknown.

However, recent reports have emerged suggesting that Haub may not have actually perished on the mountain. According to these reports, Haub had been having an affair with a Russian woman named Yelena Grigoryeva, and had fled to Moscow with her after his disappearance. The reports claim that Haub had transferred large sums of money to Grigoryeva's account before disappearing.

Grigoryeva reportedly lives in a luxurious apartment in Moscow, where she has been living openly with Haub since his disappearance. The couple has reportedly been seen dining at expensive restaurants and attending social events together.

Despite these reports, there has been no official confirmation of Haub's whereabouts or survival. Swiss authorities have stated that they are still treating Haub as a missing person until definitive evidence of his death is found.

Haub's disappearance came as a shock to many, as he had been known to be in good health and had a successful business career. He was the heir to the Tengelmann retail empire, which is one of Germany's largest retail companies. Haub had been serving as the company's CEO at the time of his disappearance.

The Tengelmann family has not made any public statements regarding the reports of Haub's whereabouts or survival. The company has also not commented on the matter.

The case of Karl-Erivan Haub's disappearance remains a mystery, with many questions still unanswered. The circumstances surrounding his disappearance and alleged survival have fueled speculation and intrigue, but until definitive evidence is presented, he will remain a missing person in the eyes of the law.
