Officials in Alabama are trying to figure out who dropped two dogs over a 6-foot fence, killing one of them.

Security camera video in Huntsville shows the person dropping the dogs over an animal shelter's fence on Monday afternoon.

Barney, an American bull mix puppy, survived the fall onto concrete and gravel. But his mother suffered head trauma and did not.

Officials at the shelter buried her on their property.

Barney is underfed and has worms but is expected to recover.

The animal shelter is called The Ark.
