Grand Theft Auto IV Walkthrough

This isn't so much a mission as it is a part of the story that segues you into the game's final mission. And it's a sad one at that. At the first 10am following the previous mission, Roman will call Niko and tell him to get his ass over to the church (this is following a call with Pegorino, and a rather unsuccessful one with Kate, who refuses to go to the wedding with Niko). Make sure you're dressed in a suit and nice shoes (which you may or may not already be), and then head over to the church, the very same one where the McReary funeral was held.

All seems great. You meet up with some old friends, such as Little Jacob and Badman, and the wedding goes off without a hitch. But Dimitri just won't stop, and when a man walks up to Niko and tells him he has a present from Dimitri, a gun discharges and goes into Roman, killing him right in front of his new wife. Niko has had enough, and shoots the corpse of Dimitri's thug over and over again before Little Jacob implores him to get out of dodge before the cops show up. He promises to be in touch on Dimitri's location, and just like that, this brief and sad mission concludes.
