SALINA, N.Y. (AP) _ Police say a 6-year-old girl has died and her teenage brother is hospitalized after carbon monoxide from a portable generator filled their home in suburban Syracuse.

The state Public Service Commission will investigate the death of the 6-year-old Salina girl to determine what role the termination of electric service at the home played. The agency routinely investigates serious accidents related to utility shut-offs.

Gabriella Collins died Friday. Her father found her and her 14-year-old brother unconscious when he returned to the house. The boy is hospitalized in critical condition.

A National Grid spokeswoman says the utility shut off power to the house in mid-August for unpaid bills. She said power couldn't be restored until the homeowner repaired a faulty grounding wire.
