Mick Jagger’s Family Seeks Help as Granddaughter’s Partner Remains Missing for Days

The partner of Mick Jagger’s granddaughter has been missing for several days in the U.K., leading the family to ask the public for assistance.

Alexander Key was reported missing in Boscastle, a coastal village in Cornwall, according to a statement from Devon and Cornwall Police. The 37-year-old chef shares two children with Assisi Jackson, the granddaughter of the Rolling Stones frontman, the BBC, Hello! magazine and CornwallLive reported.

Police initially believed Key was last seen on Friday, Jan. 23, at 2:20 p.m. local time at a pub. However, authorities later said new footage provided additional information about his movements. CCTV images show Key on Saturday, Jan. 24, at 3:25 p.m., walking past The Wellington pub on Old Road toward Boscastle Harbour, near the River Valency.

In the newly released images, Key is wearing a blue waterproof jacket over a red shirt, along with black sneakers. He is described as 5 feet, 8 inches tall with a medium build and bright blond hair. Authorities also noted that he is known to wear bright colors.

In an initial update, police said they were “growing increasingly concerned for the welfare” of Key.

Jackson’s mother, Jade Jagger, also shared information about Key’s disappearance in an Instagram post on Monday, Jan. 26. In the comments, some followers asked for more details that could help with the search, while others expressed support.

“Sharing now and sending all my love in the meantime,” wrote one user, adding they could “imagine how harrowing this is.”

Another commenter wrote, “Thinking of Assisi, Alexander and their daughters. I hope Alexander turns up safe.”

Key and Jackson have been together since 2010, Hello! magazine reported, and welcomed their first daughter in 2014.

In 2019, the couple announced they were expecting their second child, also a girl.

Anyone with information about Key’s whereabouts is asked to contact Devon and Cornwall Police.
