FAIRFAX, Va. (AP) - An FBI agent is the latest victim of the Washington-area sniper, and investigators said Tuesday they were confident that detailed witness accounts from the scene will lead them to the person who has now killed nine people.

Linda Franklin, 47, of Arlington was shot in the head Monday night as she and her husband loaded packages into their car outside a Home Depot at the Seven Corners Shopping Center.

FBI spokesman Barry Maddox said Franklin worked at FBI headquarters. A senior law enforcement source, speaking on condition of anonymity, said there were no indications that she was targeted because of her job.

Mattox added that she was not a part of the task force investigating the sniper shootings.

The Washington Post, quoting an FBI chaplain at Franklin's home, reported that Franklin and her husband were planning to move Friday to another home in the area and were at Home Depot to buy supplies for the move and the new house.

Fairfax County Police Chief Tom Manger suggested that witnesses gave investigators more details than on any of the other shootings. For the first time, witnesses were able to give information about license plates on vehicles seen leaving the scene, he said.

"There was some additional information that we were able to get from last night's case and I am confident that that information is going to lead us to an arrest in the case," Manger said at a morning briefing.
