Police shot and killed a man while trying to serve a warrant — at the wrong house

One officer fired shots at the pit bull that hurtled out of the mobile home in Southaven, Miss., police said. The other officer fired at the person pointing a gun from behind the cracked front door.

They had been trying to serve an arrest warrant in an aggravated assault case at a mobile home in the neighborhood before the sudden explosion of gunfire Sunday night. When they surveyed the aftermath, they made a heart-dropping discovery: They were at the wrong home.
