Python killed in Florida everglades - why?

so a python ate a deer and then had to be killed?  whats wrong with this story? first of all, the deer was dead, the python was just cleaning up the everglades.  second, its what pythons do. third, this is the middle of nowhere, people are not here on foot, they are safe from the python, unless they fall out of the swamp boat, drown, die, and the python eats their corpse.  Last, how did the python get there? someone dumped their pet?  It obviously was there a long time, since it was 18 feet long - obviously thriving, minding its own business.  the story said, they didnt want pythons to move further north....what?  you mean there are more pythons?  My impression is that there was just this one, and it takes two pythons to mate, unless you are Tia Tequila (who is that anyway?)  So a solitary python, who cant reproduce, who has lived in the swamp long enough to grow to 18 feet, eats a dead deer, and has to be shotgunned to death?  Why?  who will eat the dead stuff now?  Bubba and his friend?  WAIT !  I figured it out!  the python was competing with Bubba for dead deer meat - it had to be killed !
