Man gets 23 years for NE slaying

A District man who was convicted of killing another man in a dispute over a woman was sentenced to 23 1/2 years in prison, officials said. Terry Johnson, 23, was convicted in March of second-degree murder and related weapons charges stemming from the 2011 slaying of 19-year-old Andre Wiggins. Johnson and Wiggins had an ongoing feud that stemmed from Wiggins' relationship with Johnson's ex-girlfriend. The two men had ambushed and shot at each other on multiple occasions. On Oct. 26, 2011, Johnson positioned himself in an alley in Wiggins' Northeast Washington neighborhood and waited for his rival. When he saw Wiggins, Johnson ran him down and shot him, prosecutors said.

D.C. officer hurt in hit-and-run leaves hospital

The D.C. police officer who was struck in a hit-and-run in March and then waited more than 15 minutes for an ambulance left the hospital on Tuesday, NBC Washington reported. Sean Hickman was on-duty when he was injured on March 5, and he had multiple surgeries. He was taken to a hospital by an ambulance from Prince George's County because none of the District's ambulances were available. An internal investigation later found that three D.C. ambulances were improperly out of service at the time. Three men have been charged in connection with the hit-and-run.
