FORT MYERS, Fla.- A Southwest Florida woman has three extra reasons to smile tonight. The mother of three children in the military says the death of Osama Bin Laden is a landmark in the fight against terror.

"I couldn't believe it. I was like, are they sure?" Cindy Cummins Keller said Monday.

For this military mom, last night's headline hit home.

"Relief. Relief. Even more than celebration, relief," Keller said.

Three of her four children are military, and two of them are active duty. Her son Kyle, a six-year Army vet, just returned home from his second deployment to the Middle East. She says Osama Bin Laden's assassination shows every soldier's hard work has finally paid off.

"He spent the past two years of his life in the sand box, so to speak. He was very excited to find out it all happened," Keller said.

The celebration doesn't stop there. Overseas, troops tuned in to President Obama's big announcement last night, crowding around TV's.

But more than anything, Keller says it serves as a much needed morale boost for a mission ten years in the making.

"The men and women who've been over there and fighting so hard, and working with people people there to build their trust. It lets them know that it has not been in vain," Keller said.

The Keller family also has another son, who's served more than 21 years in the Navy, and a daughter with two decades of service invested in the Air Force.
