A search is underway for the missing 16-year-old child of former Slack CEO Stewart Butterfield and Flickr founder Caterina Fake, who reportedly ran away from her Marin County home Sunday night. Mint Butterfield went missing around 10 p.m. from Bolinas, and the Marin County Sheriff's Office was alerted to her disappearance at 8:30 a.m. Monday, NBC Bay Area reported.

The Sheriff's Office says Mint is about 5 feet tall and weighs approximately 100 pounds. They have brown-reddish, curly hair and pierced eyebrows. They were last seen wearing a black sweatshirt, flannel pajama pants, and black boots and may have been carrying a gray suitcase. After running away from home, family and authorities suspect the teen was headed to the San Francisco area, believed to have been headed somewhere in the Tenderloin neighborhood.

Amplifying the urgency, San Francisco Supervisor Matt Dorsey took to Twitter, requesting the public's help in locating Mint. "This is a missing child whom we now believe to be in or around the Tenderloin neighborhood here in San Francisco. If you see Mint Butterfield (see below) or have information about her whereabouts, please contact the phone number in the posting below," Dorsey posted on X.
