Another Suburban Shooting Rocks Washington By James Vicini

SILVER SPRING, Md. (Reuters) - Police in the Washington area launched a massive manhunt on Tuesday after an early morning shooting of a driver on the steps of his idled commuter bus raised fears a serial sniper had struck again.

Authorities closed major roads and checked vehicles -- especially those driven by men -- as they scrambled to determine whether the attack in Montgomery County, Maryland, was the work of the gunman who has killed nine people and wounded three since Oct. 2.

--It is becoming an armed camp around here. I have never seen so many police on the streets. Roads can be closed on a moments notice.
