The unidentified officer and a detective had arrived at the home to notify family members that Ellerbe had been killed. His body was discovered shortly after 6 a.m. Wednesday, face down near an alley.
The pitbull ran from the backyard of the home toward at least one officer, who pulled his weapon and shot the dog in the home's front yard, according to Ellerbe's sister, Latoya.
"They had told me my brother was dead and I'd come out back to cry on the porch and Tiger must have heard them. He ran into the front yard and the officer shot him," LaToya Ellerbe said.
