A prosecutor will pursue the death penalty against a western Pennsylvania couple in the starvation death of their 23-month-old daughter, who authorities say weighed just 10 pounds when she died in February.

The prosecutor's office announced its intention Friday when 32-year-old Michael Wright Jr. and 26-year-old Andrea Dusha were formally arraigned on charges of criminal homicide, child endangerment and reckless endangerment.

Authorities allege the child, Lydia Wright, was left in a car seat for more than 13 hours at the family's squalid Uniontown home before she died of malnutrition and dehydration.

The couple's attorneys didn't return calls for comment.

Wright's former attorney says Wright thought Dusha was caring for the child. Dusha's former lawyer says Dusha did "everything that she was supposed to do at the first sign of distress."
