ALTADENA ( — A 23-year-old hiker stranded in the hills of Altadena for two days was rescued thanks in part to several residents who heard her cries for help.

“I was just sort of standing here looking up there and sort of wondering and it took a little while before I heard anything,” says Frank Leonardi, who was on his patio when he thought he heard a cry.
