A close friend ofSarah Krivanek, an American woman serving a prison sentence in Russia, has written to U.S. PresidentJoe Bidenpleading for his help.
“I am begging you to please act on her behalf,” Anita Martinez wrote in a letter she says she submitted Aug. 10 through the White House website, a copy of which was shared with PEOPLE. “Do something to ensure that her basic human rights are being met and that contact is made so that we can send her the supplies needed to maintain herself.”
She was released on bail after agreeing in writing that she would not leave Moscow and would demonstrate good behavior until her trial. But on Dec. 15, she was arrested at a Moscow airport while trying to catch a plane to flee back to the U.S.
Krivanek carried with her at the airport a letter that showed she received a $200 repatriation loan from the U.S. government to cover expenses on her journey to the States. She also reportedly secured a diplomatic escort to the airport.
A State Department official previously told PEOPLE that the agency was aware of the December 2021 arrest of a U.S. citizen but said the American Embassy was not aware that she was ordered to stay in Moscow until her trial. She’s now serving a one-year, three-month sentence related to the assault charges.
“I am quite aware that Sarah may have to serve out the duration of her sentence before we can get her home,” Martinez wrote to President Biden. “My concern is the lack of communication and I worry about her well-being and mental state of mind as we do not know her current living conditions.”
Martinez cited a CNN interview withTrevor Reed, a former U.S. Marine who was detained in Russia for nearly three years before beingreleased in Aprilin a prisoner swap.
“Based on his description of what the conditions are like in Russian prisons, I am even more concerned for Sarah because we’ve not been able to send her supplies through their inmate commissary website, a phone number is needed on Sarah’s end,” Martinez writes.

“I fear that since Sarah has had nothing for over 8 months that she may be suffering from malnutrition. Even the official Russian government prison site recommends sending cartons of cigarettes to use as currency,” the letter continues. “Sarah has absolutely nothing to bargain with, I fear for her health and safety due to potential mistreatment because she is an American Citizen!”
In her letter to Biden, Martinez included information on Krivanek’s whereabouts that she received from Russian human rights activist Ivan Melnikov.
The White House did not respond to PEOPLE’s request for comment on Martinez’s letter to Biden.
Melnikov has also written a letter, which PEOPLE has reviewed. His message to Sec. of State Antony Blinken was also submitted through the White House site Aug. 4 and describes the circumstances of Krivanek’s case.
“I do not believe,” he writes, that “Ms. Krivanek represents a danger to society.”

He also says that he “firmly believes” Krivanek should be a “potential candidate in the ongoing negotiations on prisoner exchanges between Russia and the United States.”
“I have no doubt that the Russian authorities will be willing to support such a humane initiative,” Melnikov tells Blinken in his letter.

Last week, American WNBA star Brittney Griner wassentenced to nine years in prisonfollowing her trial in Russia for alleged drug smuggling.
“Russia is wrongfully detaining Brittney,” President Biden said in a statement after the sentence was announced. “It’s unacceptable, and I call on Russia to release her immediately.”
Griner is now the subject ofdiscussions on a prisoner swapbetween the U.S. and Russia, and Melnikov’s letter implies that he hopes Krivanek’s fate will also be considered.
But Griner’s and Krivanek’s cases are different, according to Chris Costa, a 34-year veteran of the Department of Defense and former U.S. Army Intelligence officer who is now theexecutive director of the International Spy Museum.

“She is a victim, but she might not be a wrongfully detained, that’s a category,” Costa told PEOPLE in an interview last week. “She was defending herself, but that doesn’t mean she’s wrongfully detained in accordance with Russian law.”
He also emphasized that a determination of whether a prisoner is wrongfully detainedbased on the Levinson Actis likely ongoing and could certainly change over time.
“It’s an analytical judgment based on the facts of the case. But it’s kind of a sliding ruler based on the situation. It’s dynamic, too, because new facts can come to light and political environments can be revealed,” he said.
Letters written on Krivanek’s behalf could help, given the intense coverage in the media of Griner’s case and the outpouring of support for her and calls to bring her home.
“Sarah’s family could be optimistic that the United States is really redoubling,” Costa told PEOPLE. “We are committed to taking care of U.S. citizens held abroad wrongfully.”
