Alexandria Police Chief Earl Cook solicited residents’ assistance in turning up leads Monday’s deadly shooting of a prominent D.C.-area transportation planner.

Cook said at a Thursday press conference that police want to hear from anybody who had spoken socially with 69-year-old Ronald Kirby, the longtime director of transportation planning with the Metropolitan Washington Council of Governments, within the last three to four weeks, along with anyone who saw anything out of the ordinary in the neighborhood Monday.

“We don’t want potential witnesses to qualify their own information,” he said. “They need to tell us, and then we’ll assess the information.”

Cook did not share any new details of the investigation, on which police are working around the clock, but said the department does not yet have any persons of interest.

“We don’t have that person at this point,” Cook said. “We cannot exclude anyone.”

Kirby was found around 12:30 p.m. Monday by a relative in his home. An autopsy revealed that he had suffered multiple gunshot wounds to his torso.

Cook reiterated that residents in the Rosemont neighborhood should not feel threatened by the recent incident of violence.

“We don’t think we have a crazed killer,” he said.

Police are urging anyone with information to contact the department’s criminal investigations section at 703-746-6711 or at 703-746-6864.
