In the days that followed, in between sharing news stories about her husband, Gounder tweeted out photos of happy memories of Wahl, from a friend's wedding in Paros, Greece earlier this year to a shot from their 2018 Thanksgiving celebration.

Gounder, who was previously named one of PEOPLE's 25 Women Changing the World in 2017 — married Wahl back in 2001. Together, they share two dogs — Coco and Zizou.

Another photo shared by Gounder shows the couple celebrating the wedding of a friend in 2000, prior to their own marriage. Wahl, who regularly referred to his wife as "Doc" on social media, wrote on Instagram that she proposed to him in 2000 in New York City, where they both resided.

Gounder met her husband when they both studied at Princeton in the mid-'90s, and currently works as Senior Fellow and Editor-at-Large for Public Health at the Kaiser Family Foundation and for Kaiser Health News, is a contributor at CBS News, a professor at the NYU Grossman School of Medicine and also cares for patients at the Bellevue Hospital Center.

On Monday, a State Department official confirmed that Wahl's body had returned to the U.S.

"At this point, we will defer to the family to speak to the next steps," State Department Spokesperson Ned Price said during a press briefing. "I know that they have spoken publicly to their wishes and of course, we worked very closely with the family over the past 48 hours to help fulfill those wishes."

Wahl's brother, Eric, said on Twitter that he and Gounder will take Wahl's body for a "medical examination" and "autopsy."
