“BALTIMORE—Omar Little, the veteran stick-up artist who inspired fear and fascination in drug-plagued neighborhoods across the city, was shot and killed in a west-side convenience store yesterday.Police said the assailant remained at large.

Famed for his brazen robberies of area drug dealers, Mr. Little had retired from what he called “the game” a year ago, moving to the Caribbean with a new romantic partner. But he apparently returned to Baltimore this winter to seek revenge following the brutal murder of a beloved business associate.”
