Brianna Zani sporting various looks. The 21-year-old has been missing since Thursday.

UPDATE: Ms. Zani has returned to her Jefferson Street apartment in the last half-hour and is waiting in an ambulance in front, with her parents, reports her downstairs neighbor on Twitter. Zani’s sister is expressing her thanks to the people who helped spread the news.

On March 17, one day after Bushwick resident Brianna Zani stopped taking her bipolar disorder medication, she went missing. Two days later, the 21-year-old with a history of mental illness was found passed out in alley and taken to Woodhull Hospital where she quickly escaped. Now her family is coordinating a growing search effort, both in North Brooklyn and online.

Using Facebook, Twitter, Craigslist, and every possible internet resource, Zani’s family is hoping to speed up the hunt for the girl, who they say is most likely “disoriented.” Zani originally left her Bushwick apartment without her wallet or cell phone around 11 p.m. Tuesday night. After her second disappearance, her sister Amelia Zani created a web site that has been shared and reposted by hundreds through Twitter.

The Zani family says 50-60 people have helped distribute over 2,500 flyers, and many of them can be seen posted in various places in Bushwick. Everyone is encouraged to print and distribute the flyers, available in English and Spanish.

After her escape from Woodhull, Zani apparently stayed the night with someone and left in the morning. After she left, her boarder saw the flyers and called the tip lines. This person reports Zani was calling herself “Bruboxer” or “Brubaker.”

Zani is 5’6, 165 lbs., has blues eyes and blond hair (though she may have shaven it off) and was last seen wearing a green shirt, black beanie hat and yellow sunglasses. She was last seen at 212 Throop Avenue in Bedford-Stuyvesant. If found, her family asks that people call 911 and stay with her.
