NORRISTOWN (AP) - Relatives say a 12-year-old boy died when he returned to a burning suburban Philadelphia house to search for his father who just had hip surgery.

The boy's grandfather Kenneth Peterson tells WPVI-TV (http://6abc.cm/1TJjzsJ ) the father survived by jumping out of a second-floor window.

Authorities say five family members were in the Norristown home when the fire broke out just before 9 a.m. on Friday. One man was taken to hospital.

The boy's name is not being released. Fire officials say an autopsy is scheduled for Saturday, when more information will be announced.

Norristown is about 20 miles northwest of Philadelphia.
