And at about 12:30 a.m. Monday, police reported finding a man fatally shot in the 2900 block of Mosher St. His name has not been released.

The tactics police are calling on to reduce homicides this month are modeled after similar tactics used to quell a string of violence last fall that the commissioner blamed on gang fighting.

Between late October and late November, eight people were shot in several incidents along a stretch of Greenmount Avenue, and police pulled 150 officers from administrative positions to bolster patrol units.

The agency also provided district officers for two weeks to the regional Warrant Apprehension Task Force, made up of law officers from the city and Baltimore County, and the U.S. Marshals Service. That move resulted in arrests or cleared warrants on more than 300 cases, including charges of assault, burglary and lesser crimes and violations. The same task force is being counted on to reduce crime this time around.

In the Western District, police plan to send in more special units, including plainclothes officers, to bust up drug rings, gather sources and help out with arrests. Guglielmi said these sorts of surges in enforcement have proved effective. Just last month, police focused on hunting down suspects with outstanding warrants related to robberies.

Pulling more officers from administrative positions to foot patrol also helps make up for 150 patrol vacancies that police have been unable to fill, which could almost make up an entire district by themselves, Guglielmi said.

John Bullock, neighborhood president of the Evergreen Protective Association in West Baltimore, said he welcomes more patrol officers. He said he has noticed a resurgence of loitering around the Evergreen Lawn neighborhood.

"The one thing we're seeing: more people occupying corners and streets," he said. "And more foot patrol would help. Every time a police car would show up, people do disperse."
