Deadshot mission

[Your Grandpap]

I can't find a way to trigger the second deadshot victim. I've completed the main story but the victim isn't appearing. Is there something certain I have to do to make deadshot shoot someone?

Check your map, then click through the side missions. The 2nd Deadshot victim may already be visible on the map. If not, review this thread:

If those location triggers don't work, you might need to traverse the map from end to end until you hear a gunshot, perhaps even traverse the subway from end to end. You might also checkpoint inside an interior location such as the Museum or Sionis Steel Mill and quit the game, then restart and listen for the gunshot and look for the mission prompt so you can consult your map for the victim location.
