Philadelphia boy becomes home fire's 3rd victim

PHILADELPHIA (AP) — A 5-year-old boy on Saturday became the third member of his family to die of injuries suffered in an arson fire in their home.

Moses Serrano died shortly before 6 a.m., said Andy Smith, a spokesman for Temple University Children's Hospital.

His mother, Tracey Williams, 25, was dead at the scene of the March 30 fire, and her 7-year-old daughter, Jessica Espinosa, died the next day.

A third child, William Serrano, 3, remained in critical condition at the hospital, Smith said.

Police said Arnold Blackwell, 19, of Philadelphia, admitted setting the fire in the city's Fishtown section. Blackwell had been staying in a basement apartment with his girlfriend. They escaped unharmed.
