Anne Arundel County Police said Friday that they expect to conclude their investigation into the fatal shooting of a Siberian husky at a Severn dog park by a federal officer in the next 72 hours, and they indicated that the unidentified officer might not have been authorized to carry a firearm.

The department released a redacted version of the police report of the shooting of the dog, named Bear-Bear. Department officials released a statement Friday saying that after further investigation, the officer's "legal authority to carry a firearm became questionable."

The department still has not named the officer, who they said fired his personal weapon in the shooting.

Police said they initially closed the incident, and that the State's Attorney's Office, after reviewing the case, instructed the officers not to file charges.

The officer's attorney, David Putzi, said this week that his 32-year-old client was acting in self-defense in an attempt to stop an attack on his dog, a German shepherd named Asia.

But Rachel Rettaliata, the husky's owner, said the dog has a history of being friendly. Her brother had taken 3-year-old Bear-Bear for their daily trip to Quail Run community dog park when the husky was shot.

Rettaliata said her brother told her that the dogs began to play roughly and that the off-duty officer asked him to call off the dog. But before he could move, the officer shot Bear-Bear, she said.

The investigation is ongoing.
