He wounds in Brooklyn, kills in Manhattan

A man was shot to death in a lower Manhattan public housing complex Monday by a gunman who also blasted a 96-year-old man with bullets during a robbery gone wrong in Brooklyn earlier in the day, police sources said.

Sundance Oliver, 28, started his rampage near Bergen St. and Rochester Ave. in Bedford-Stuyvesant around 9:35 a.m., according to police.

The elderly man was in a motorized wheelchair about 75 feet from where Oliver was sticking up a woman, sources said.

Oliver was aiming for the woman but hit the victim in the leg, instead.

The victim was rushed to Kings County Hospital, where his wife told the Daily News he was recovering.

Hours later, police clocked Oliver’s white Mercedes-Benz coming over the Brooklyn Bridge into Manhattan, sources said.

Around 2:50 p.m., shots rang out in a sixth-floor apartment in the Smith Houses on St. James Place near Catherine Slip steps from NYPD Headquarters, cops and sources said.

A 21-year-old man identified by friends and family as Kavon Langston was shot twice in the chest and once in the leg.

Oliver ran off and police later found his white Mercedes in the parking lot, sources said.

Langston was rushed to Bellevue Hospital, where he died.

His distraught brother struggled to make sense of the killing after the shooting. “That was my brother,” said the man, who would not provide his name. “He never had no problems with anybody. We can’t believe this.”

The victim’s mother and sister, who were in the apartment but were not shot, were taken to the same hospital for observation, sources said.

“When I came up, there was a woman screaming in the hall that he’d been shot,” said a neighbor, who also asked not to be named. “Then there were police everywhere.”

Police are still looking for Oliver, who previously served time behind bars in upstate Seneca County for robbery, records show.

He himself has been shot three times this year alone, sources said.

Oliver’s alleged attack marked the second fatal shooting in public housing Monday, cops said. A man was shot in the head outside the Marcy Houses in Bedford-Stuyvesant around 3:40 p.m., police said.
