1 0 0In Infamous 2, Dead Drops are now indicated by bird icons flying around in the circle. You'll see these as you are transversing around town. I found these while I was looking for all the blast shards using the blast shard sense. There is a Dead Drop near where you started New Marais if you are missing one.
