A dog was found beheaded on a walking trail near the Iowa River in Marshalltown.
Heidi Drager with the Marshalltown Animal Rescue League said the dog was a pit bull less than 6 months old.
The dog's body was found lying in the branches, and hatch marks and blood spatter were found on a log nearby. Drager said a machete or an axe was used to kill the dog. Its head is still missing.
"(We're) trying to find some information out from the community if anybody knows who might have done this, so we can get some answers for this dog," Drager said.
