Questions answered in this file

What is holdback evidence?

Details of a crime that investigators keep from the public so they can test the credibility of confessions, tips and witness accounts.

Why do police keep details from families?

To prevent information spreading to the public or the person responsible, which could undermine future confessions or prosecutions.

How do holdback details leak?

Through court filings, released records, media reports, social media posts or conversations among people with access to the case.

Should researchers publish details they suspect are holdback?

Consider carefully whether publication adds public value, and ask the investigating agency whether it could harm the case.

Can holdback justify withholding everything?

No. Families deserve basic information about the death and case status, and public records laws limit what agencies can withhold.
