(April 9): The wife of an amateur hiker, who went missing while trekking in the Ghorepani area of the Khopra Danda Trek, in Nepal on Sunday, is now in the country to help coordinate rescue efforts.

The family told media tonight that Jennifer Eileen Peters-Lee had flown to Nepal on Wednesday and that they anxious about the safety of businessman, Dennis Lee Thian Poh, as it has been more than four days since his disappearance.

"At this time, independent search and rescue teams have been sent out but the inclement weather has caused delays."

Lee, 48, was reported missing in the Ghorepani area of the Khopra Danda Trek on Sunday, about 3pm local time (5.15pm Malaysian time).

The family said the father-of-two is an amateur hiker and regularly treks in the Malaysian jungles. He is also fit and athletic, and had recently climbed Malaysia's highest peak, Mount Kinabalu in Sabah.

They said that Lee arrived in Kathmandu on March 28, to go on a hiking trip on the Annapurna circuit with a group of friends from the Philippines. Lee was the only Malaysian in the group of nine.

"They were two-thirds of their way through the trip when Lee went missing... The group was travelling from Khopra Danda to Duerali.

"The group had already reached the highest point of their trek and this was the first day of the descent.

"It was at some point during this part of the trek that Lee went missing," the family said.

The guide, the family said, turned back and tried to retrace the route to locate where Lee could have strayed.

"By Tuesday, a search party of 35 people had been put in place. A police report was lodged and Jennifer was informed about 6.30pm (Malaysian time) by the company he used, Holiday Tibet Trek.

The family added that they are now seeking the help of the Nepalese authorities to assist in the search.

Thanking everyone for their support and prayers, the family said they had created a Facebook page, Find Dennis, for those who wish to share information or express support for his safe return.
