Mick Jagger’s family is reaching out to the public for assistance in locating Alexander Key, the long-time partner of the rock legend’s granddaughter, Assisi Jackson. Key, 37, has been unaccounted for since Saturday, following his last sighting at a pub in the picturesque coastal village of Boscastle, Cornwall.

Disappearance Timeline

According to Devon and Cornwall Police, Alexander Key was last seen on Friday, January 23, at approximately 2:20 p.m. while enjoying a drink at the Cobweb Inn. However, updated CCTV footage revealed that he was spotted later, at 3:25 p.m. on Saturday, January 24, walking past the Wellington Pub and heading towards Boscastle Harbour and the River Valency.

Key is described as standing at five feet eight inches, with a medium build and distinctive bleach blond hair. He was reportedly dressed in a patterned red shirt and black sneakers at the time of his disappearance. His partner, Assisi Jackson, 33, and their two young daughters have been anxiously awaiting news.

Family’s Plea for Information

Jade Jagger, Key’s mother-in-law and daughter of Mick Jagger, took to Instagram to share details about Key’s disappearance. In her post, she included two photographs and urged anyone with information about his whereabouts to contact the police immediately. Georgia May Jagger, Mick’s youngest daughter, echoed this call for help on her Instagram Story, providing the police’s contact details and urging the public to act quickly.

A Life Together in Cornwall

Key and Assisi have been together for over a decade, carving out a life on a sheep farm in Cornwall, where they are raising their daughters. Key is known as the chef and co-owner of The Rocket Store, a seafood restaurant in Boscastle. Assisi, the eldest of Mick Jagger’s seven grandchildren, spoke previously about the family’s tendency to have children young and how her own experiences shaped her life decisions.

“Growing up quite quickly, I wouldn’t have considered having a child if I was doing what my friends are doing at this stage, messing around,” she remarked in an interview with Hello! magazine, reflecting on her journey into motherhood.

As the search for Alexander Key continues, local authorities have released additional images to aid the investigation. They have reiterated the importance of community involvement in locating him. The police have established a dedicated log number—847 of January 24, 2026—for anyone who may have information to facilitate the search.

The Jagger family’s appeal has captured the attention of the public, with many expressing their support and concern. The outpouring of community spirit highlights the importance of collective efforts in times of distress.

Why it Matters

The disappearance of Alexander Key is not just a personal tragedy for the Jagger family; it highlights a broader issue surrounding the safety and well-being of individuals in our communities. Cases like these remind us of the fragility of life and the critical role that public vigilance plays in ensuring the safety of our loved ones. As the search unfolds, it serves as a poignant reminder of the ties that bind us and the collective responsibility we share in looking out for one another.
