Search for Mick Jagger’s Granddaughter’s Missing Partner

Police in southwest England are urgently seeking information after Alexander Key, the long-term partner of Assisi Jackson — a granddaughter of Sir Mick Jagger — was reported missing on the afternoon of Friday, 23 January 2026 in the seaside village of Boscastle, Cornwall.

Key, 37, is believed to have been last seen at around 2:20 p.m. local time at a local pub in Boscastle. Devon and Cornwall Police were alerted to his disappearance on Saturday evening, prompting an urgent missing-person investigation.

Who Is Alexander Key?

Alexander Key is a chef and co-owner of The Rocket Store, a well-known seafood restaurant in Boscastle Harbour that emphasises local produce and community engagement. He and Assisi Jackson have been in a long-term relationship for over a decade, and together they have two daughters, aged 11 and 6.

Assisi Jackson, 33, is the eldest granddaughter of Rolling Stones frontman Sir Mick Jagger and the daughter of Jade Jagger, who has publicly shared the police appeal on social media to help trace Key. Jade Jagger’s post includes CCTV images of Key and urges anyone with information to contact authorities.

Police Description and Appeal

Officers describe Key as:

• Medium build

• Bright peroxide-blonde hair

• Often seen in brightly coloured clothing, including an orange-patterned jacket captured in CCTV footage shortly before he vanished.

The police appeal stresses that people who may have seen him on Friday afternoon or know of his whereabouts should contact Devon and Cornwall Police immediately, quoting log number 847 of 24 January 2026 when calling.

Community and Family Concern

The disappearance has drawn significant concern from both family and the local community. Assisi Jackson’s mother, Jade Jagger — herself part of one of the world’s most famous rock families — has used her platform to amplify the appeal, sharing photographs and urging anyone with possible sightings to come forward.

Search efforts remain ongoing, with police continuing to investigate Key’s last known movements and to speak with potential witnesses in the Boscastle area.
