Date not specified in current profile sources — Graff Diamonds robbery. conspirator; convicted

Status and record

The structured birth record lists circa 1967. The structured life-status field is alive. This administrative field should change only when a reliable current source supports an update.

Source record

The current Master package attaches the following evidence sources to this profile: – Four robbers convicted over £40m Graff diamond heist — The Guardian, Tier 2. – Two in court and a third charged with £40m London jewellery heist — The Guardian, Tier 2.

Each source supports only the claims tied to it. Structured source references remain attached so later audits can trace timeline and relationship records back to evidence.

Evidence and editorial boundaries

For living subjects especially, legal claims and current status require dated sourcing. Future expansion should therefore come from stronger records or newly processed canonical entities rather than unsourced crime lore.

How this profile fits the archive

The current source package includes Four robbers convicted over £40m Graff diamond heist; Two in court and a third charged with £40m London jewellery heist. These records define the safe editorial boundary for the page. A later pass should prioritize new primary documents, court outcomes, dated organizational changes, prison history or newly processed books and screen works rather than adding generic background.

Research state

This depth pass expands the page from structured evidence already present in the Master. The profile should return to audit when a new source materially changes chronology, legal status, organizational role or media connections. Add the structured fact first, then update prose so narrative and knowledge graph remain synchronized.

Media remains a separate gate. A portrait should be attached only after source page, provenance and reuse status are checked. Until then, a profile can be text-complete while still carrying an explicit media-review requirement.
