He was getting ready to spend his retirement in India. Relatives said he worked hard, sent money to his father in India and helped bring his siblings to America. He was a quiet man with a good sense of humor, they said.

- Lori Ann Lewis-Rivera: A neighbor says she was a "very nice and sweet lady" who doted on her preschool-aged daughter and "provided everything for her." Lewis-Rivera, a 25-year-old resident of Silver Spring, Md., was killed while cleaning her van at a Shell station. She had moved into a garden apartment about a year ago with her daughter and husband, but dreamed of moving to a house.

- Pascal Charlot: The 72-year-old from Washington, D.C., was a carpenter who immigrated from Haiti years ago. He fixed things for his neighbors - a doorjamb for one, a box around a radiator for another. He lived with his wife in a rowhouse decorated with potted flowers on the porch and tomatoes and bell peppers in a small garden.

- Kenneth H. Bridges: The 53-year-old father of six from Philadelphia had co-founded a marketing and distribution organization and was a graduate of the University of Pennsylvania. Bridges was president and chairman of the board of MATAH Network, an organization formed in 1997 to encourage blacks to support black-owned businesses and to promote black self-sufficiency. He is described by neighbors as "very friendly, very friendly." Bridges' wife was concerned because he was going to the Washington area for a business trip.

- Linda Franklin: The 47-year old Arlington, Va., resident had beaten breast cancer, raised two children and a niece practically by herself and was expecting her first grandchild in just a few months. An intelligence specialist with the FBI, Franklin’s smile "could light up a room," coworkers said. "Extremely outgoing," Paul Hulseberg said of his friend. "Probably the most giving person I know." Franklin is survived by her husband and two grown children, a son and daughter. The daughter is five months pregnant.
