Police have named the bus driver believed to be the 10th fatal victim of the US serial sniper. Conrad Johnson, a 35-year-old father of two, was shot as he stood at the top of the steps of a bus stop in Montgomery County, Maryland.
The location, 15 miles north of downtown Washington, is less than half-a-mile from the scene of the first shooting on October 2nd.
"We remain concerned about the safety of all the people in our region," said police chief Charles Moose.
"We realise that the person or the people involved in this have shown a clear willingness and ability to kill people of all ages, all races, all genders, all professions, different times, different days and different locations," he said.
Police put a widespread dragnet into place, clogging traffic on Connecticut Avenue, one of the main routes into Washington, just as the morning commute began.
Johnson, a 10-year county employee, had been taken to Suburban Hospital in Bethesda. The shooting happened near an apartment building and wooded area along Connecticut Avenue. The bus was parked at a staging area where drivers get ready for their morning runs.
Police closed roads around the shooting scene and set up roadblocks at points along the Capital Beltway.
Teams of officers stopped all cars driven by men, not just white vans which have been the focus of earlier sniper shootings.
