PALM HARBOR, Fla. (AP) - A Pinellas County Sheriff's deputy shot and killed a pit bull that attacked a drug suspect's girlfriend.

 Deputies had just arrested Michael P. Walker and were leading him to the patrol car Monday night when they heard growling and yelling inside the house. Walker told deputies it sounded like his 7-year-old pit bull Mojo was attacking his girlfriend, Sheena Sovine.

When Deputy Christopher Brady went inside the home, he found the dog attacking the woman. He tried to distract the dog, but it started attacking him. Brady then shot the dog, which died at the scene. Sovine was taken to the hospital with bite wounds to the arm and shoulder. Brady was not injured.

 Walker was taken to the Pinellas County Jail. --- Information from: St. Petersburg Times, http://tampabay.com
