Noting the phrase scrawled on many of the plastic water jugs -'buena suerte,' or 'good luck' in Spanish - the prosecutors said: 'The obvious conclusion is that the defendant and No More Deaths wish to aid illegal aliens in their entry attempt.'

Prosecutors had requested a $5,000 fine, along with five years of probation, according to court documents after Staton initially refused to pay a $175 fine for littering, according to Staton's lawyer, Bill Walker.

Mike Hawkes of the Buenos Aires National Wildlife Refuge said Thursday that although he had no issue with groups leaving water out for illegal immigrants, 'there's ways to do it without leaving plastic jugs out there.'

He said the plastic jugs were strewn throughout the refuge, which is home to hundreds of bird, reptile and mammal species.
