12 years later: The Madeleine McCann case may be one of the most poorly investigated

Over the past twelve years, I have given a handful of interviews about this case and written on particulars of the investigation.

If a background check was run on you, here’s what would be in it

You’ve probably wondered at some point: If someone ran a background check on me, what would be in it?

Believe me when I say you would be shocked at what’s actually in these reports: I’m a private investigator whose agency performs hundreds of these background checks and asset searches every year.

The sheer amount of data in these reports is staggering: Many of them are a hundred pages or more.
