LOS ANGELES — After a weekslong battle with a mysterious illness, Big Bear’s beloved bald eagle Jackie died early Monday morning at an Ojai rehabilitation center. Not long after, Sandy Steers, executive director of Friends of Big Bear Valley, died after a private battle with cancer. Since Jackie’s rescue, fans have wondered what will become of Shadow and the life she left behind in Big Bear. Before her death, Friends of Big Bear Valley acknowledged it’s impossible to know what the future holds. Shadow, who is 12, could find a new mate or even leave the Big Bear area.
