UPDATE: Rookie is now at the Oklahoma State University Veterinary College Teaching Hospital where he is currently in stable condition.
The veterinarians will attempt to repair and save Rookie's shattered leg Monday.
The Oklahoma County Sheriff's office is still asking for information in this animal cruelty case.
Anyone who saw the crime or has information is asked to call the OCSO.
OKLAHOMA CITY - A German Shepherd dog was critically injured after being thrown over a bridge, high above I-40 Wednesday afternoon in eastern Oklahoma County.
The animal is now being cared for by a local veterinarian as Oklahoma County Sheriff's Deputies search for the person responsible.
Authorities learned from the original owner that the dog's name was "Rookie."
He's lucky to be alive.
"Yes, because he could have gotten hit by a car or anything could have happened after and who knows how long he laid out there," Kate Bellah said, Deer Creek Animal Hospital veterinary technician."
"This is just a tragic, really sick situation," Sheriff's Spokesman Mark Myers said. "For someone to take a defenseless dog and just toss it off of a bridge over a major interstate, I really don't understand how someone could do something like that."
Myers said a truck driver traveling along I-40 saw the incident while nearing the S.E. 59th St. bridge.
An OHP trooper found him bleeding profusely with an open fracture on his leg, as well as skid marks.
Injuries so bad, he can't have surgery just yet.
"Well, if he's in shock or anything like that, it would be a lot harder for him to go through anesthesia and pull through," Bellah said. "We want to make sure he has plenty of fluids and blood and that type of thing."
While everyone is wondering who could have done such a thing, the big question is will Rookie survive?
"I don't know what the outcome is going to be with the fracture but he has a good chance right now," Bellah said.
We're told Rookie was in critical but stable condition Thursday.
The Humane Society of the United States is covering the cost of the veterinary care and they're offering a $2,500 reward for information leading to an arrest.
Bellah said the OHP officer who found Rookie on I-40 is interested in adopting him.
They are also offering a $2,500 reward for information leading to the person's arrest.
Anyone with information is asked to call the Oklahoma County Sheriff’s Office at (405) 869-2501.
