Louisville, Kentucky. -- A mystery in Shelby County has people on high alert.

Something is on the prowl, attacking animals and leaving them for dead.

People say a creature attacked six goats -- five of which had to be put down -- and four calves in the past couple weeks.

Rusty Newton, Deputy County Judge Executive, says, "It's not doing it to kill the animal to eat, these animals are just being mauled. That's where the mystery is at this point."

Neighbors say it lurks in the woods, and only comes out at night. No one has seen the creature, but people are on the lookout. A couple found what they believe are tracks from the animal.

Frank Edwards lives in the area. He says, "We've got trail cameras out, we've got traps out it's like it's smarter than we are."

County officials are holding a meeting Monday night at 6:30 in Waddy to inform neighbors.
