Family wants answers after police shoot, kill dog in their backyard Days before Christmas, a family on the Westside buried their dog after an officer shot and killed him. Now, the owner is demanding answers. A police report from The Jacksonville Sheriff's Office says Officer Victor Jones was responding to an alarm going off at the house Wednesday afternoon.

A police report from The Jacksonville Sheriff's Office says Officer Victor Jones was responding to an alarm going off at the house Wednesday afternoon. The officer said that he went around the back to check for any signs of forced entry when the dog in the backyard approached him in an aggressive manner. He shot him in the head in response.

Matthew Long said his 11-year-old dog, Prophet, wasn’t aggressive.

Long posted about the matter on Facebook which was shared nearly 30,000 times.

Long has hired an attorney from Louisiana, who is partnering with a Jacksonville firm to help him with his case.

Long's lawyer, Tarak Anada, said he thinks Prophet did what dogs do when they're startled. "Did I see a situation where this officer was in danger of losing his life or grievous bodily harm, such that, the use of lethal force was justified? Absolutely not."

Anada also says he didn't have to use lethal force, but that he could have used a Taser or pepper spray. "This was a preventable tragedy. The shooting was a result of poor planning, poor preparation, poor training, and just a lack of experience of dealing with a family's dog."
