When unexpected people start coming forward with new evidence—documents, messages, photos, devices, witness accounts—the safest and most responsible response is:

1. Hand it directly to authorities

Give it to:

• Guardia Civil
• local police
• a solicitor/lawyer who can transfer it properly
• relevant safeguarding or investigative authorities

That protects chain of custody.

2. Do not investigate it yourself

The instinct is often:

• “Who sent this?”
• “What does it mean?”
• “Let me look deeper.”

But that can create problems:

• accidental evidence contamination
• altering metadata (opening files can change timestamps)
• alerting suspects
• putting yourself at risk

Curiosity can unintentionally damage a case.

3. Do not tamper with evidence

Avoid:

• editing screenshots
• forwarding repeatedly
• renaming files
• plugging devices in “just to check”
• deleting anything

Even well-meaning handling can complicate forensic analysis.

4. Preserve what you received

Do:

• keep original messages/emails
• note when/how it arrived
• keep devices powered state unchanged if possible (ask police first)
• save voicemails/texts exactly as-is

Simple notes like:
“Received on Tuesday at 10:42 from unknown number”
can help investigators.

5. Let investigators investigate

Once authorities have it, the process moves to:

• evidence triage
• forensic examination
• witness interviews
• legal authorizations if needed

That’s their role—not yours.

Psychologically this can be hard because humans want closure and answers.

But in these situations, restraint is often the most helpful act:
don’t chase the truth—protect it.

That gives investigators the best chance of finding out what’s really going on.
