During a news conference on Monday, officials said the crimes were all gang-related. In all, 14 people are facing a total of 120 charges between them.
That includes four adults and three juveniles who are charged with first-degree murder.
Officials say these indictments are a step toward justice for victims' families.
"Our hearts go with the families, who have suffered the greatest loss and borne the terrible weight of gun violence. Wilmington is a small city, and these families are our neighbors," said Delaware Attorney General Kathy Jennings.
The group is suspected in several other attempted murders and is facing a long list of weapons charges.
The suspects, and the charges against them, include:
