PITTSBURGH—A death penalty trial has begun for a man accused of having set a house fire that killed a young child and two women in Pittsburgh 4.5 years ago.
Martell Smith, 45, faces three counts of homicide as well as aggravated arson and other charges in the early morning December 2017 blaze in the Homewood neighborhood, which Allegheny County prosecutors say he set after getting into a bar fight with another man.
