Elizabeth Holmes, the founder of disgraced biotech firm Theranos, was still in possession of a one-way ticket to Mexico shortly after she was convicted of fraud last January, prosecutors said Thursday.

Holmes was found guilty on four counts of lying to investors on Jan. 3, 2022. According to a Thursday court filing, on Jan. 23, 2022, the U.S. government became aware of the ticket for a flight to Mexico departing Jan. 26, 2022 without a scheduled return trip.

In the response filing, prosecutors characterize her itinerary as “an attempt to flee the country.”

“Only after the government raised this unauthorized flight with defense counsel was the trip canceled,” prosecutors said.

It is not clear when Holmes originally purchased the ticket. In response to a Jan. 23, 2022, query about the ticket from the case’s lead federal prosecutor, an attorney for Holmes characterized the situation as a misunderstanding, according to an exhibit also filed Thursday.
