yes that is a body alright... not sure its the real Pac's body , but anywayz..
he might be alive and he might be dead , nobody knows.
there are theories about him , about him changing his name to Makavelli in his last year(makavelli is famous in the past for his dissaperance and returning rich)
There are songs in witch he sais just random shit , but when ya hear it backwrds it sounds like "Yes i'm alive , i'll be back"
Plus there is this video about him.. dunno f its fake but here it is : http://www.youtube.com/watch?v=r3YBCQPKsUc
Notice the guy in the dark shirt comming towards the camera , sais "Hide pac man"
and here is the song where he sais "yes i'm alive,am'a missin you" :
