"My son went into harm's way because of the actions of this evil person, so I can't say I'm not glad he's off the face of the earth," she said. "And I am glad that our servicemen and women have seen this day come."
She said she's worried, however, that the killing of bin Laden might spark revenge from other al Qaeda operatives.
"I concerned now about retaliation," she said. "I'm worried that more innocent, good people in this world are going to die."
She added that she's trying to maintain a sense of perspective - she's avoided watching the repetitive news reports, because she doesn't want to relive the horror of her brother's death.
Following the terrorist attacks, she was at Ground Zero and shedding tears, watching rescue workers on their hands and knees digging through the rubble for remains of loved ones. Weeks later, she attended a somber memorial ceremony there. For a long time, her grief was like a living nightmare, she has said.
"I'm now trying not to dwell on it - I don't like to have that wound reopened all the time," she said Monday. "It's not going to change my life at this point - My son is home, he's safe."
She said, however, that the 115-month-long pursuit of bin Laden by the U.S. military and security forces makes a powerful statement to the world about America's resolve and determination to see justice accomplished.
"It's been a long time coming," she said. "It sends a message that Americans don't give up."
Instead of dwelling on her family's heart-wrenching loss of her brother, Patricia Frasco spent time on Monday with her son Brad and his wife Laura, who just brought their new baby home from the hospital.
During the visit by his mother, Brad received a text message from a friend who expressed the hope that the military strike that concluded with bin Laden's death created a safer world for Brad and Laura's brand-new baby girl to live in, Patricia Frasco said.
"The message touched Brad," she said. "The cycle of life is going on."
