I was looking at MPs on Interpol and found one Dzmitry Dalnikouski, a native of Belarus, who disappeared from Las Vegas in 2004.
Out of curiosity I Googled his name and found this police blotter: Dzmitry Dalnikouski, age 29, was arrested in a Chicago suburb for something or other back in July. I wonder if I should phone this in. The name and age are exactly right. Honestly though I don’t know who to get in touch with.

It says call national or local police…..maybe if he disappeared from vegas call them?
Weird. I would probably call LVPD. I couldn’t get the interpol link to work though…
Wow – he so doesn’t look 20 in that Interpol photo. IMHO.
He probably wasn’t. A lot of those pics look very out of date.
Here’s a link to Interpol, maybe you should start there?

Or, as other have suggested, contact LVPD
Would it help at all if I made a couple calls for you? I live 10 minutes away from the Dominicks that he robbed, so I’m close enough that I could probably talk to the local police and get some records for you if that would help.
I don’t need any records but if you want to tip them off that he’s listed as missing with Interpol, being a local you might do a better job than I could.
Makes you wonder what he might of been up to in Belarus before he went missing here.
Who knows. Belarus is not the best place — it’s kind of famous for being the last dictatorship in Europe, as well as being one of the poorest and most backward countries on the continent. That the Soviet way of life is over, is news to them.
I’d really love to visit though.
