Police say Alexander Key, the partner of Mick Jagger’s granddaughter, went missing in Boscastle, a coastal village in Cornwall. Early reports placed him at a pub on Friday afternoon, but investigators later uncovered new CCTV footage that extended his known movements into the following day.

The updated images show Key walking past another pub on Saturday afternoon, heading toward Boscastle Harbour near the River Valency. He wore a blue waterproof jacket layered over a red shirt, paired with black sneakers. Officers describe Mick Jagger’s granddaughter’s partner as someone known for wearing bright colors, a detail they believe could help witnesses recall seeing him.

As days passed without word, Jade Jagger, the mother of Mick Jagger’s granddaughter, publicly asked for help by sharing details of the disappearance online. Messages of support quickly followed, with many expressing concern for both Key and the two young daughters he shares with Mick Jagger’s granddaughter.

The couple has been together since 2010 and built a quiet family life away from constant public attention. That privacy has made the situation especially difficult, as loved ones now rely on strangers for information. Police continue to stress that even small details could matter, and they urge anyone who may have seen Key to contact authorities as soon as possible.
