The investigation into the death of the 9-year-old schnauzer named Tywinn started in December when a janitor found the dog in a trash bag in a bathroom stall at Orlando International Airport.

ORLANDO, FL -- A Louisiana woman was arrested and charged Wednesday after she allegedly drowned her dog in a bathroom at Orlando International Airport last year. According to the Associated Press, the woman -- who was not named by the AP -- was charged with one count of third-degree animal cruelty, and posted $5,000 bail.

Instead of calling someone to pick up the pup or missing the plane, the ghoul allegedly took her dog to a restroom ahead of the security checkpoint and drowned the poor pooch, Orlando police said.
