Police stopped motorists outside the entrance of the Central Intelligence Agency Tuesday, seeking eyewitnesses to Monday's shooting spree that left two agency employees dead and three injured.
With the killer still loose, police were looking for rush-hour commuters who may have seen the gunman as he stood on the highway and fired at point-blank range into cars stopped at a traffic light.A police spokesman said officers were getting "numerous responses" from the motorists they stopped Tuesday. Police were showing sketches of the killer, described as a young man in his 20s, who escaped in his car after the shooting.
At CIA headquarters several hundred yards away, shocked officials were considering an array of new safety measures for the sprawling suburban Virginia complex.
Agency officials were working with police organizations in an effort to find the gunman.
Fairfax County Police Chief Michael Young said authorities had compiled a list of possible suspects based on information from witnesses and survivors, and a composite sketch was being circulated.
Police also were working with a CIA-supplied list of employees and contractors who might have been disgruntled and had a motive for the shooting, officials said.
"CIA employees are shocked and saddened at the senseless attack on our friends and colleagues," said a statement issued by the agency.
