PITTSBURGH -- A house fire that killed a 4-year-old girl and two women in Pittsburgh has been ruled an arson.

Authorities say 41-year-old Martell Smith allegedly set the fire that broke out early Wednesday. He allegedly had been involved in a bar fight earlier that night with a relative of the victims who also lived at the home.

Smith faces three counts of homicide, along with arson and drug charges, while 26-year-old Tiasia Malloy is charged with aggravated assault on an officer. It wasn't known Thursday if either one has retained an attorney.

The victims were identified as 4-year-old Chy'enne Manning; her 21-year-old mother, Shamira Staten, and 58-year-old Sandra Carter. A man who jumped to a neighboring home's roof to escape the blaze suffered a leg injury.
