Speck said her dog, who was in her backyard, was barking hysterically.
Concerned that the tiger now posed a threat to others, the officers chose to fatally shoot the animal.
As the school day approached, officers also said they didn't want any children to be in danger as they waited at their bus stops.
The Henry County Police Department and animal control are now working to determine where the tiger came from.
It is thought the tiger was fully-grown but it is not known where the tiger came from.
While responding officers kept visual on the tiger, it began to run to the back of a residence in the Meadow Brook community and began to attack a dog. The small dog survived, but the tiger did not. "It was a tiger on the far side, closest to my house", she said.
