A 19-year-old man was shot several times last night in a stairwell at the Hannibal Grove apartment complex, and investigators were questioning a 15-year-old boy about the shooting, police said.
The shooting occurred about 8:45 p.m. at the complex, located in the 5300 block of Brook Way, after the victim became involved in an argument with two teen-agers, police said. The injured man was flown to the Maryland Shock Trauma Center in Baltimore, where he was listed in stable condition with at least four gunshot wounds.
