Three teenagers were wounded in a spate of shootings near several schools in the Congress Heights area of Southeast Washington on Thursday. D.C. police said a weapon was recovered and two people were detained for questioning about the three shootings, which all happened at about 9:30 a.m. But investigators say they are still determining what sparked the shootings and whether they are related.

The two people in custody have not been charged, said Officer Araz Alali, a D.C. police spokesman.
