How to Restart Qeynos Badge Quest

[skwayb]

I messup the second quest and hit Theodore Exanthem early and he died.

Since I don't have the first badge anymore from the turning, I tried restarting the first quest over but I can't get the Investigator to give me a confession Document.

I killed Guard Shilster and turned in his helm to Vegalys to get the Investigator's Briefing and then when I had that to the Investigator nothing happens and when I say "Hand me a Confession Document", to the Investigator in South Qeynos, nothing happens.

How do I restart the quest?
