Where do they end up finding Richard Parker in Life of Pi?

Richard Parker is actually a 450 pound, male Bengal tiger
who escaped the sinking of the ship. Pi helped the tiger climb on board the lifeboat,
knowing that man and tiger won't necessarily co-exist. When Pi's lifeboat finally
drifted across the Pacific and grounded itself on the Mexican shores, Richard Parker
jumped from the boat and scampered off into the jungle without so much as looking back.
There he could find the food and water he desperately needs to survive. At the end of
the story, no trace of Richard Parker was ever found. The reader is left to ponder which
story Pi told was the real one.
