Wall Street Journal reporter Evan Gershkovich has been wrongfully detained by Russia for 100 days

Friday marks 100 days that Wall Street Journal reporter Evan Gershkovich has been detained by Russia during a reporting trip and accused of espionage, making him the first American journalist held by the Kremlin on such charges since the Cold War.

"Every day that Evan isn’t home is another day too many. We miss our son and will not stop until he is free. We are so appreciative of all the support from around the world. It’s overwhelming, and we are grateful," Gershkovich's family said in a statement Friday.

"It's hard to believe Evan is coming up on 100 days," Lucian Kim, a friend of Gershkovich and former NPR Moscow correspondent, told Fox News Digital. "I think of him every day, in that jail cell in one of Moscow's most notorious prisons, a young journalist now accused of espionage just because he tried to tell the story of Russia — a country we know less and less about."

"At the same time, I know Evan to be an immensely positive person, and I think the knowledge that so many people on the outside are supporting him helps him a lot. I've had limited communications with Evan. But I have let him know that he has many, many friends who are waiting until the day he walks free."
