FBI: Washington shooter may be Marine

WASHINGTON, Oct. 29 (UPI) -- A U.S. Marine with a grudge may be behind a series of shootings at government targets in Washington, officials said Friday.

The National Museum of the Marine Corps in Quantico, Va., became a target Thursday night for the second time, The Washington Post reported.

The FBI said its agents are working on the assumption the same person is behind that shooting and three earlier ones. The agency said Thursday the same gun was used to fire at the museum and the Pentagon Oct. 17 and 19, and this Tuesday at an empty recruiting office in Chantilly, Va.

At a Washington news conference Friday, FBI officials said the gunman should surrender to authorities. They did not give details on why they believe the shooter is likely to be a Marine.

Museum employees found bullet holes in a window Friday morning. The shooting occurred while the museum was closed overnight.

Gwenn Adams, a spokeswoman, said the museum was shut down for the day while investigators examine the scene. She said it was expected to reopen Saturday morning.
