Convict: Cynthia Anderson, 57 (pictured), was convicted of drowning a puppy in a Nebraska airport

A July sentencing has been scheduled for a 57-year-old Florida woman convicted of drowning a puppy in a Nebraska airport restroom.

Cynthia Anderson, of Edgewater, pleaded no contest on Thursday and was convicted of cruel neglect of an animal resulting in its death.

She faces up to five years in prison on the felony charge. Her sentencing is set for July 30.

Anderson had been accused of trying and failing several times to sneak the young Doberman onto a plane.

According to multiple reports, police said she tried boarding a January 22 flight at the Central Nebraska Regional Airport in Grand Island with two dogs in crates and three puppies.

The Orlando Sentinel reported dogs younger than eight weeks old are not allowed to fly.

'Their eyes weren't even open,' Grand Island Police Captain Dean Elliott told the newspaper.

Sgt. Stan Steele with the Grand Island police department told the Grand Island Independent Anderson handed off two of the puppies to her parents.

Steele told the newspaper Anderson tried to get on a January 23 flight with the two dogs and the remaining puppy in her carry-on luggage.

Anderson was barred from boarding that flight at the Central Nebraska Regional Airport because the puppy was so young and not properly contained.

Authorities say Anderson then was seen entering the restroom. Another woman soon reported finding a dead Doberman puppy in a toilet.

An officer report obtained by The Smoking Gun said 'On my arrival I learned a 3 week old puppy had been drowned in the toilet after a woman tried three times to get it on the plane.

'The woman was arrested after speaking with her and numerous witnesses.

'The puppy was taken to the Humane Society and autopsied.

'It was was found to have water in one of its lungs.'

According to the Grand Island Independent, the Central Nebraska Humane Society has two of the other puppies.
