The teenage daughter of the billionaire co-founder of software company Slack Technologies has disappeared, and the Police fear she may have run away to one of the most dangerous neighborhoods of San Francisco, US media report. The 16-year-old Mint Butterfield is the daughter of Canadian Stewart Butterfield - former CEO of Slack - and his ex-wife, billionaire co-founder of Flickr, Caterina Fake. The girl was last seen on Sunday in Bolinas, California, and her mother reported her missing on Monday, according to local media. Authorities fear she is in San Francisco's Tenderloin district, about 50 km from Bolinas, a law enforcement official familiar with the case told NBC News. Local officials have told the media that the teenager has previously used drugs and is known to frequent the Tenderloin, an area with a high crime rate notoriously linked to the drug world. According to NBC, the 16-year-old was living with her mother at the time of her disappearance and attended a local private boarding school. As reported by the Marin County Sheriff's Office, on Monday morning around 09:02, Mint's mother, Caterina Fake, reported her daughter missing, last seen around 22:00 the day before at their home in Bolinas. According to her testimony, the girl had left the residence with a suitcase during the night or early morning. It is not clear at this time how the sixteen-year-old would have done so, considering she had no access to a vehicle or a phone. According to the police, Fake and Mint also share a house in San Francisco, and based on the mother's statements, Mint may have left for the Tenderloin district of San Francisco. The possibility of kidnapping is excluded at the moment. The sheriff's office is indeed treating the case as that of a voluntarily missing minor, at "risk" however due to a previous suicide threat. Marin County deputies have entered Mint into the Missing and Unidentified Persons System (MUPS) and have sent All Points bulletin flyers to surrounding law enforcement with a description and photograph of Mint.
