WASHINGTON (WUSA9)--Sixteen year-old Leilani Tizon is a courageous teenager who talks candidly about an issue rarely discussed in public: suicide.
It's the 10th leading cause of death for Americans, and it leaves shattered families in its wake.
"It sounds harsh but I've spent the last five years thinking that my brother doesn't love me. And that this is my fault," Leilani told us, from the living room of her suburban Washington home.
Growing up, Leilani and Christopher Tizon were inseparable.
"My brother and I were best friends. We were 6 ½ years apart," she said. "He was 18 when everything happened. I was 11."
Their father, Robert, was on a deployment to Saudi Arabia with the Air Force, when Christopher put a loaded gun to his left temple and pulled the trigger.
"He was very handsome," said Leilani, glancing over her shoulder at a large framed photo of her brother. She smiles.
