Mick Jagger’s granddaughter Assisi Jackson’s partner, Alexander Key, 37, is missing and was last seen in Boscastle, Cornwall, around 2:20 pm on Friday the 23rd of January.

Police and family are coordinating ongoing public appeals for information as searches continue along the coastal town and surrounding terrain.

Key is described as medium build with bright peroxide blonde hair and typically wears brightly colored clothing.

The story is situated within broader public interest due to coverage from outlets like Daily Mail and The Sun, and context includes the Stones’ 2024 Hackney Diamonds tour.

Coverage from TMZ and The Telegraph underscores ongoing media attention surrounding the case.

Hello magazine interviews provide background quotes about Assisi and her family, including themes of motherhood and family dynamics.

Further background covers Key’s family life and Assisi’s reflections on motherhood, while the focus remains on the missing-person case.

The disappearance coincides with recent Rolling Stones news, including a 2026 UK/Europe stadium tour that was ultimately scrapped due to Keith Richards’ availability.

A Rolling Stones spokesperson indicated future touring would be pursued when feasible, adding context to the family’s heightened public profile.

Authorities and the family warn of the urgency and promise to provide further updates as new information emerges.

A past anecdote about Mick Jagger at a separate event is noted but not directly related to the disappearance.

Searches face challenges from the coastal environment and winter conditions in Boscastle, raising safety concerns for Key and responders.
