Mick Jagger's Granddaughter's Partner Missing: Cornwall Search for Alexander Key (2026)

A desperate search is underway for a member of Mick Jagger's family, as the partner of his granddaughter Assisi Jackson has gone missing in Cornwall. This heart-wrenching situation has the family and authorities on high alert. But who is this missing person, and why is their disappearance so concerning?

The individual in question is 37-year-old Alexander Key, a chef and father of two children with Assisi, 33. Alexander was last spotted in the charming coastal village of Boscastle on Friday afternoon, but his absence was only reported to the Devon and Cornwall Police the following evening. This delay could be crucial in the investigation, and it's a reminder that time is of the essence in such cases.

Assisi's mother, renowned jewelry designer Jade Jagger, took to social media to share the police appeal, including images of Alexander. The police describe him as having a medium build and a distinctive look with bright peroxide blonde hair and a penchant for colorful clothing. And here's where it gets intriguing: in the shared images, Alexander is wearing an eye-catching orange patterned jacket, a potential clue to his whereabouts.

The police are deeply concerned for Alexander's welfare, especially given the treacherous nature of the Boscastle area, known for its dramatic cliffs and harbor. This picturesque village attracts visitors year-round, but its beauty can be deceiving, especially during the winter months.

The family connection to the Rolling Stones frontman is undeniable. Assisi, the eldest grandchild of Mick Jagger, is the daughter of Jade Jagger and her former partner, artist Piers Jackson. Assisi and Alexander reside in Cornwall, raising their two daughters, Ezra (11) and Romy (6). Alexander is a co-owner of a popular seafood restaurant, The Rocket Store, known for its fresh ingredients, including fish caught by Alexander's father and meat from their family farm.

But here's where it gets controversial: the interior of the restaurant features a painting by Assisi's father, Piers, depicting a star constellation. Some might say it's a unique family affair, while others may question the potential conflict of interests.

Adding to the family dynamics, Jade Jagger gave birth to her son Ray just weeks after becoming a grandmother to Assisi's daughter Ezra. This unusual timing is a fascinating twist in the family's story.

As the search for Alexander continues, the family and police are appealing to the public for any information. The question remains: what led to Alexander's disappearance? Was it a tragic accident, or is there more to this story? Share your thoughts and theories in the comments below, but remember to be respectful and considerate of the family's privacy during this difficult time.
