A mix of nine goats and sheep, plus two rabbits were killed overnight at The Urban Farm at Stapleton, a nonprofit that teaches urban families about agriculture.
Denver police said Sunday morning that they were investigating the deaths of several animals at the proximate location of the farm. The nonprofit's president told Denver 7 that about a dozen goats, sheep and rabbits were killed.
Denver Police Spokesperson John White said that two large mixed breed dogs were found on the scene and that police did not receive any reports of gunfire in the area that night.
"Animal control is looking into the possibility that the dogs may have been involved," said White. "The state veterinarian is on scene, along with members of Denver's animal control, documenting the scene and the exact cause of death."
Police are still investigating people who may be connected to the dogs.
