The 16-year-old daughter of billionaire Slack co-founder Stewart Butterfield vanished and is feared to be in one of San Francisco’s most notoriously dangerous neighborhoods.
Mint Butterfield, 16, was last seen at 10 p.m. Sunday in Bolinas, Calif., according to Marin County Sheriff spokesperson Deputy Jose Suarez.
Butterfied’s mother and Flickr founder Caterina Fake, reported the teen missing on Monday, according to the San Francisco Standard.
They had been living with her Fake at the time of her disappearance and were attending a private boarding school in the Napa area, according to the sheriff’s office.
“Mint was last seen wearing a black sweatshirt, flannel pajama pants, and black boots, sheriff’s officials said. They were also possibly carrying a gray suitcase,” Suarez wrote in a statement.
However, the 5-foot-tall teen with curly, brown-red hair and pierced eyebrows is believed to have run away to Tenderloin, which is known for its violent crimes, rampant homelessness, and open-air drug market in downtown San Francisco.
Mint Butterfield allegedly has a history of substance abuse and has been known to frequent Tenderloin in the past, the outlet added.
“Please contact Marin County Sheriff’s Office with any information on their whereabouts,” Suarez wrote.
Stewart Butterfield co-founded messaging app Slack in 2013 but left the company after Salesforce acquired the platform for $28 billion in 2021.
According to Forbes, His net worth is around $1.6 billion.
Fake founded the imaging service Flickr with Butterfield in 2004 and sold the company to Yahoo! in 2005 for around $30 million.
Fake and Stewart Butterfield married in 2001 but divorced in 2007 — the same year their daughter was born.
