You will receive this task only if you've killed Jarrad in [The Elimination Job].
On your way to Zah Dan, you will come across Mirrda by the gate (M12:18), who wants to avenge his brother's - Jarrad's - death. He will be accompanied by a thug. The fight shouldn't be hard, just kill both of them to end the matter.
