Police: No evidence of shooting at Washington Navy Yard

WASHINGTON (AP) — Investigators found no evidence of a shooting after the Washington Navy Yard went on lockdown today because someone reported shots fired in the same building where a gunman killed 12 workers in a rampage two years ago.

D.C. police said a woman called from inside a Navy Yard building to report that she might have heard sounds of gunshots around 7:20 a.m. However, investigators found no sign of a shooting, a shooter or anyone injured.

No arrests were made and no weapons found, officials said.

"At this time there is no evidence of gunshots," Mayor Muriel Bowser said. "There is no evidence of a shooter, and there is no evidence of any victims today."

A U.S. official who spoke on condition of anonymity said Navy security saw surveillance video of two people jumping the fence in the vicinity of the building a couple of minutes before the first report of gunfire. Security found no one inside the building, the official said.

Officials do not believe the report was a hoax, D.C. police Chief Cathy Lanier told reporters. Investigators interviewed the woman who made the call, Lanier said, and she did exactly as authorities regularly tell people: Report anything you think may be suspicious.
