Sergei - Grand Theft Wiki, the GTA wiki

Sergei is a member of the Faustin Family and appears in Grand Theft Auto IV. He was Mikhail Faustin's bodyguard.

There is some confusion about the killer at Roman's wedding being Sergei. Although they share the same NPC model he isn't the assassin. Some aesthetic differences being the voice; Sergei was voiced by Jeff Norris, while the killer was voiced by Jacek Krawczyk. And another that distinguishes the two is height. Sergei is at least 5 inches taller than Niko whereas the assassin is the same height or at least 2 inches taller.

Trivia

If the player would have failed the random encounter with Mel the first time, the second time, when talking to Niko, he'll mention that one of his reasons to stop drinking was "not hanging around with losers like Sergei". Given the fact that Rockstar tries to avoid giving the same name to two characters in the same game, Mel could be talking about Sergei.
Sergei bares a large resemblance to Agent 47 from the Hitman series, with the same suit and both of them are bald.
Dimitri mentions him during Final Destination, saying that Segei has a friend in the courts.
