Over a span of two days D.C. police made arrests in a February shooting and a September stabbing that helped close two violent crime cases.
On March 17, authorities said they arrested Delonte Mack, 29, Southwest, for suspected involvement in a Southwest shooting that happened on Feb. 25.

Last month, a officer was patrolling in the Unit Block of N Street, SW when the officer heard the sound of gunshots nearby, police reported.
Officials said the officer found a man lying out front of a restaurant on N Street, SW suffering from several gunshot injuries.
The victim had been struck by gunfire in his buttocks, groin, foot and shoulder. The victim was taken to a local hospital and treated for his injuries.
Mack was arrested and charged with assault with intent to kill while armed. Mack is scheduled to appear in court for a preliminary hearing on March 31, D.C. Courts said.

Authorities arrested Jeffrey Saunders, 31, and charged him with assault with intent to kill in the stabbing of a man on Sept. 27.
Police said they found a man suffering from multiple stab wounds in the hallway of a Southeast apartment building around 2:55 a.m.
A witness said he heard a woman screaming and came out into the hallway to see the victim on the floor face down bleeding from his injuries, police reported. The victim was taken to a local hospital and was treated for life threatening injuries.
On Jan. 13, Chiquita Harris, 30, a resident of Southeast D.C., was arrested and charged with intent to kill in connection with the stabbing.
