Scott Walter Cahill

James Cahill was two blocks from ground zero on Sept. 11, close enough that when he ran out of his office building he could see the hole the first jet tore into the World Trade Center.

Two things came to mind: One was a sense of "devastation," he said.

The other was that his son was in there.

Scott Walter Cahill, 30, worked as a municipal bond broker for Cantor Fitzgerald. He is missing and presumed dead.

On Sept. 30, his family held a memorial service at St. Aloysius Church in Caldwell, N.J. Cahill, who was unmarried, lived with his dad, his mom, Linda, and his 9-year-old brother, Patrick.

"We were a pretty tight family," James Cahill said.

Scott Cahill sometimes took family vacations with his parents and younger brother. But he also liked to travel on his own, mostly on ski and snowboard vacations to Utah, British Columbia and Austria. No matter where he traveled, he made friends. According to his father, he could make conversation with anyone, anywhere, anytime.

Cantor Fitzgerald has announced it will distribute a percentage of profits for the next five years to the victims' families. The Cahills have set up a fund in their son's name to help pay for new science equipment at the local Catholic school.

"It keeps his spirit alive," James Cahill said.

Sean Rooney

After the first plane hit the north tower of the World Trade Center, Sean Rooney called his wife, Beverly Eckert, who was at work in Stamford, Conn. He left a message that he was OK in his office at Aon Risk Services in the south tower and planned to be there for a while, since they had secured the building.

Then a plane hit the south tower. Eckert had gone to the couple's Stamford home, where Rooney soon called. He told his wife he was trapped on the 105th floor of the burning building. He had made several attempts to escape--first trying to run down the stairs, only to be beaten back around the 76th floor by heat and smoke. Then he tried to access the observation deck just above his office, but couldn't because the door was locked.

Rooney, 50, was having difficulty breathing. The couple began talking about their life together and their love for each other.

"I heard him say, `I love you,' then I heard a terrible explosion and a roaring sound," Eckert said. "It sounded like Niagara Falls. I knew without seeing that he was gone."

The couple were together for 34 years, meeting in high school in their native Buffalo. Rooney, a vice president at Aon, enjoyed an array of sports, including golf, tennis and in-line skating. He was a gourmet cook, helped restore the couple's home and even built their kitchen table, his wife said. His acerbic wit was memorable, she added.

"There's no way I can summarize my feelings for Sean in a story or a thought," Eckert said. "There's really only one story: It's a love story and it lasted 34 years."

Stephen Patrick Cherry

Stephen Patrick Cherry was two weeks shy of his 42nd birthday when he disappeared in the Sept. 11 terrorist attacks on the World Trade Center, his family said.
