"I knew he was smart, I didn't think he was that smart," the victim's fiancee, Miesha Lucas told MyFOXMemphis.com. "He was always protective. I didn't think he would be like that."

Police refused to name the victim as they do not plan to file charges in the shooting, which they've ruled as accidental.

Lucas told MyFOXMemphis.com that she fears what her fiance will do to the pet once he gets out of the hospital.

The shooting occurred in the Raleigh section of Memphis.
