Amy Schneider, Jeopardy! champion and the show's highest-earning female contestant tweeted on Monday that she had been robbed over the weekend.
Schneider, 42, made history in November as the first trans contestant that qualified for the Tournament of Champions.
She tweeted, "So first off: I'm fine. But I got robbed yesterday, lost my ID, credit cards, and phone. I then couldn't really sleep last night, and have been dragging myself around all day trying to replace everything."
The robbery occurred just days after Schneider won her 21st consecutive game, breaking the record for most wins by a woman. Julia Collins set that record in 2014. Schneider, an engineer manager living in Oakland, Calif., currently has 25 wins to her name and has earned $918,000 in winnings so far. That also makes her the highest-earning woman to play.
A spokesperson from Jeopardy! told NBC News in an email that they had reached out to Schneider to offer their support.
"We were deeply saddened to hear about this incident, and we reached out to Amy privately to offer our help in any capacity," the spokesperson said.
Oakland police confirmed to NBC News they were investigating a robbery that occurred Sunday, but did not identify the victim.
Candace Kea, a police spokesperson, told the outlet in an email that two people, including one who was armed, fled after robbing the victim of "personal belongings."
By Tuesday afternoon, no arrests had been made.
Over the last couple of weeks, the gameshow champion has had to defend herself against internet trolls who repeatedly misgendered.
"I'd like to thank all the people who have taken the time, during this busy holiday season, to reach out and explain to me that, actually, I'm a man," she tweeted. "Every single one of you is the first person ever to make that very clever point, which had never once before crossed my mind."
Schneider told Oakland TV station KGO-TV last month that she hopes to inspire others.
"I am so incredibly grateful," she said. "Hopefully I can send a positive message to the nerdy trans girl who wants to be on the show too."
