Step 220 of 248 in the playthrough
Professor Drake turns in the last piece of evidence to Lt. Toft aboard the UC Vigilance thus ending the quest.
This begins when the UC SysDef quests begin and ends when all pieces have been turned in.
No video, most of the evidence can be found during the course of the UC SysDef quests against the Crimson Fleet. The final piece that isn't in a location visited as part of those quests is on the bar in Hopetown.
