A man who was stabbed in 2009 in the Shaw neighborhood has died, and D.C. police said Wednesday that his death has been ruled a homicide. He is the second person in the District in recent weeks to die from injuries sustained in attacks from years earlier.

The victim from Shaw was identified as Jose Lopez, 39, of Northwest. Police said he was stabbed on April 18, 2009, in the 1400 block of Eighth Street NW.

He died at a rehabilitation hospital on June 14. Police said in a statement that the Office of the Chief Medical Examiner determined Lopez died of “complications from multiple stab wounds.” Details of the stabbing were not immediately available.

On Monday, police said Darren N. McManus of Northwest died on May 8 of complications from stab wounds he received on June 4, 2004. Police said he was attacked about 11:30 p.m. in the 4700 block of Sheriff Road NE. The circumstances were not described.

After the assault, police said, McManus was hospitalized and then released. But this past April, police said, he went to a hospital and died.

No arrests have been made in either stabbing.

Both deaths are counted in this year’s homicide statistics. The District has had 120 homicides in 2015, compared with 80 at this time in 2014. There were 105 in all of last year.

In addition, several people were shot in the District on Monday night and early Tuesday.

Two people were shot in the 1100 block of Eaton Road SE about 7:30 p.m. Monday. Police said one died and the other was in critical condition. The shooting occurred in the Barry Farm neighborhood, just off Suitland Parkway, in an alley.

Police identified the person who died as Ernest Massenberg-Bey Jr., 21, of Southeast. The second victim was not identified. It was the second fatal shooting in Barry Farm this week.

Another man was shot shortly after 10 p.m. Monday near 46th and G streets Southeast. Police said that person is expected to survive.

About 12:30 a.m. Tuesday, police said an armed security guard at an apartment complex in Northwest shot and wounded a gunman during a confrontation in the 1300 block of Fort Stevens Drive, off Georgia Avenue in the Brightwood neighborhood.

Aquita Brown, a D.C. police spokeswoman, said the armed man confronted the guard, a special police officer, and the two exchanged words. Brown said the man shot the guard, who fired back and struck the gunman.

Police did not identify the security guard. Authorities charged the suspected gunman, Renard Hampton, 41, of Northwest, with assault with intent to kill. Their conditions were not disclosed.
