Trey Joseph Frederick,20, will now serve 11 months in federal prison for violating the terms of his probation from the Eastern District of Texas.

Frederick's original probation sentence given in October of last year, was five years in length. He had pleaded guilty to violating the Endangered Species Act after he was convicted for shooting Whooping Cranes on Blair Road in Jefferson County in January 2016.

After an investigation, it was revealed that Frederick was seen in that area with a hunting rifle and he claimed he was hunting geese at the time.

While at his residence, Frederick was then contacted by Federal Agents where he admitted to killing the cranes.

Whooping Cranes are a migratory bird species that are classified as endangered as identified in the Endangered Species Act, making capturing, killing, trapping,collecting or the attempt of acting in such ways toward Whooping Cranes illegal in the United States.

On Thursday, Frederick returned to federal court because he violated his probation terms by using an AR-15 assault rifle to hunt from a roadway in Jefferson County, among other things.

Frederick's probation terms specifically prohibited him from owning or possessing firearms, or any kind of dangerous weapons.

He is also not allowed to fish or hunt anywhere in the United States.
