What evidence should corroborate a mobile location record?¶

A mobile location record is strongest when independent evidence supports it.

What this means¶

Cell-site data, Wi-Fi connections, Bluetooth pairings, IP records, photograph metadata, map activity and vehicle systems may all help.

Then consider real-world evidence.

CCTV, witness accounts, travel records, payment transactions, access-control systems, parking records and work logs can support or challenge the device location.

Communications may also matter.

Messages, calls, photographs and app activity may place the user in a particular context.

But corroboration should not simply repeat the same source.

Two apps may rely on the same underlying operating-system location.

That is not the same as two independent measurements.

Timing is critical.

A location point recorded at 14:00 may represent collection, upload or later processing.

Also separate device from person.

Possession, account use, CCTV, witnesses and behavioural evidence may be needed to connect the device to the user.

Where records conflict, preserve the differences and investigate them.

The operational takeaway is: corroborate mobile location through independent technical and real-world evidence, and separately establish who controlled the device at the relevant time.

What to check or do next¶

• Start with other technical sources.
• Compare time zones, device clocks, provider timestamps and synchronisation delays.
• Do not force every source into agreement.

Evidential limits¶

Evidence that the phone was in an area does not automatically prove who carried it.
