NEWARK - An internal investigation is underway after a police involved shooting Friday left a dog dead.

The incident happened on Pennsylvania Avenue in Newark. Officers were looking for someone needed for questioning when they ended up in the wrong yard. Bryan Smith, the dog's owner, says he thought police had left the area so he let Mula out in the yard.

However, police were still on the property. Police say the dog barked and charged at the officers. That's when one officer shot Mula. Police took Mula and her owner to the Associated Humane Society, but because the bullet hit her spleen the decision was made to put her to sleep.

The Office of Professional Standards is investigating the shooting. Mula's owners aren't considering a lawsuit at this point, but hope that the investigation leads to the officer being reprimanded.
