Michalski remained in Hungary for a final night while Gretchen Tower moved on to visit some friends in Italy, the grieving friend told WKBW.
The duo remained in communication until shortly after midnight Tuesday. Michalski then failed to check out of her Airbnb or make her flight back to the US — prompting Tower to call the US Embassy.
At a candlelight vigil in Budapest Saturday, Michalski’s father Bill said she had visited Budapest before, and called it her “happy place.”
