tracking down

It isn’t a skepticism that encourages consulting accredited experts or peer-reviewed research, tracking down solid sources or anything beyond cursory searches.

I travelled across America, from the suburbs of Ohio to the desert of Palm Springs, tracking down men affected and confronting those involved – including the middleman himself.

Clearly, tracking down hoaxers presents a significant challenge.

Authorities said they worked out the identity of the so-called "Pinnacle Man" after finally tracking down and matching Grubb's fingerprints.

Plus, as I found tracking down the writers for Channel3Now, the people involved in posting false information are often based abroad, making it a lot trickier to take action against them.
