More shots were fired overnight at the National Museum of the Marine Corps in Triangle, Va., according to Prince William County Police.
The shooting incident apparently occurred just hours after the FBI linked Tuesday night's shooting at a Marine recruiting center in Chantilly, Va., with two similar cases in the commonwealth -- including an earlier incident at the museum.

Some perp is playing a "cat & mouse" game.

Update: Not much except for the FBI asking the shooter to give himself up:

WASHINGTON – As authorities investigated a fourth nighttime shooting at a Washington-area military building, the FBI urged the unknown gunman to surrender before someone is hurt.
"We appreciate that he is struggling right now," FBI spokeswoman Katherine Schweit said Friday. "This guy hasn't hurt anybody. We don't think he wants to. We're hoping that he'll turn himself in."
Police in Virginia are investigating an overnight shooting at the National Museum of the Marine Corps, the fourth such shooting at military-related buildings in the area.
