Utility finds 3 more natural gas leaks in Seattle



SEATTLE (AP) -- One of the two people injured in a Seattle natural gas explosion and fire has been released from the hospital.

Harborview Medical Center spokeswoman Susan Gregg says David Ingham's wife, Hong, remains in serious condition in the intensive care unit.

Meanwhile, utility crews have found three more natural gas leaks in the north Seattle neighborhood where a home exploded, injuring two residents in a two-alarm fire.

Puget Sound Energy spokeswoman Martha Monfried says the pipes have been dug up for repair.

More than two dozen utility employees are using sniffer equipment to sweep the area within five miles of Monday's blast.

Puget Sound Energy says the leaks were apparently caused by corrosion from electrical current after a tree knocked down a wire Sunday.
