Russian teams searching for a Littleton police officer who went missing while climbing Mount Elbrus have called off their search efforts, according to the missing man’s wife.

Steven Beare has been missing since June 16 from a solo ascent of the tallest mountain in Russia.

“The Russian teams will be calling off their search after the day is done…” Olivia Beare, Steven’s wife, said on Facebook. “There is just too much snow and harsh weather conditions to continue.”

Beare, a Colorado National Guardsman who has deployed multiple times, went missing while climbing in the Caucasus region of southern Russia. Mount Elbrus, at 18,510 feet, is also the tallest mountain in Europe.

A search of the mountain led by an American will continue “day by day,” Olivia Beare said.

“Life itself as I know it is looking extremely bleak…” she said.

In another post, Olivia, who is 11 weeks pregnant with the couple’s second child, said she’s still holding on to hope.

“I just want you all to know that I am not giving up…I believe he is alive out there somewhere hanging on by a very very thin thread.”
