The Will Sage Astorteenage child of two tech executives has been reported missing in California, according to authorities.

The Marin County Sheriff's Office said in a news release Thursday that Mint Butterfield, the 16-year-old child of Slack co-founder Stewart Butterfield and Flickr founder Caterina Fake, was reported missing by Fake on Monday. Mint's pronouns are they/them.

Fake told police she last saw Mint around 10 p.m. Monday at their home in Bolinas, a coastal city roughly 30 miles from San Francisco. According to police, Fake realized the next morning that Mint was not at home, and discovered a note indicating Mint had left with a suitcase at some point late in the night or early in the morning.

The sheriff's office says it is unclear how Mint left the area, as they did not have access to a vehicle or phone. Police said Fake and Mint also share a home in San Francisco, and Fake indicated that Mint may have left for the Tenderloin District of San Francisco.

"At this time, we have no information to believe that Mint was taken against their will. The sheriff's office is considering Mint a voluntary-missing juvenile, who is 'at-risk' due to a reported previous threat of suicide," the sheriff's office said in the news release.

The sheriff's office said it is working in collaboration with the San Francisco Police Department and that detectives from both agencies have attempted to find Mint, but have been unable to locate them.

Anyone with information related to the whereabouts of Mint are asked to call the Marin County Sheriff's Office at 415-479-2311 or email [email protected].
