  Go to Comrade's Bar and talk to Vlad. He will show you a picture of a man named Mr Faustin, who Vlad says is plotting to rob Roman. Vlad asks you to kill his man, Ivan.

  Leave the Comrade's Bar and start driving to Ivan's location. When you get close, he will leave and you'll have to chase him. Follow Ivan to a construction site, and climb up both sets of ladders. Jump off the edge of the platform onto the roof.
