Where can I find Report from Wortham and Villager's Journal?

I found the report on a dead body named Wortham Villager Corpse, he was very well marked and appears to be a non-random encounter. It was just prior to getting to Leoric's palace as @Alok mentioned, in the Northern Highlands.

The Villager’s Journal spawns in a Old Keepsake Box at the Old Ruins, it was previously reported in The Lyceum a random dungeon whose location is discussed in this thread. It was unobtainable prior to patch 1.0.3, which led to most of the confusion around it but it is now dropping again.

As of 1.0.3, the Villager's Journal can now be found in the keepsake box in the ruins of Old Tristram.

Also, as of 1.0.3, the Lyceum is no longer bugged. It is found in the center of the Southern Highlands as described in the posts above.
