MULBERRY, Fla. (AP) - Authorities say a central Florida man stabbed his girlfriend, killed his dog and then wounded himself.
    
The Polk County Sheriff's Office reports that 55-year-old David McCorkle and his girlfriend came out of their home, covered with blood, when deputies responded Tuesday. Authorities say McCorkle told a deputy to kill him and threw a butcher knife at the deputy.
    
Deputies say McCorkle stabbed the woman several times with the butcher knife. Authorities say McCorkle killed the couple's pit bull mix when it tried to defend the woman.
    
The girlfriend was also armed with a knife when deputies arrived, but McCorkle said his wounds were self-inflicted. Both were taken to a nearby hospital.
    
McCorkle faces charges of attempted murder, aggravated assault of a law enforcement officer and animal cruelty causing death.
