Chicago police are investigating after two separate shootings overnight left more than a dozen people injured.
In both incidents, police were responding to a call of a person shot when they discovered multiple victims had sustained gunshot wounds following an exchange of gunfire by two people that fled the scene.

According to authorities, six people were wounded by gunfire. A male, 25, was transported to a nearby hospital in fair condition, while the others -- an 18-year-old female, two 23-year-old males, a 20-year-old female and a 15-year-old male -- were transported to nearby hospitals in good condition.
No one was in custody and an investigation remains ongoing, police said.
The shootings come on the heels of another mass shooting that took place early in the morning on the Fourth of July holiday, in the city's Grand Crossing neighborhood.
In that incident, two adults and one child were killed and two other young children were critically injured when multiple people pulled up to a residence and began firing at the home.
According to Don Jerome, Deputy Chief Area One, the shooting was believed to have stemmed from a "personal dispute." All victims were believed to be inside the residence when the shooting occurred, Jerome said.
"This senseless violence has to stop," Desmon Yancy, Fifth Ward Ald. said during a press conference Thursday. "Personal conflict and guns has become a bad combination. The summer's just getting started. I don't want to stand in front of another group of microphones and have another discussion about the pain that's caused in our community."
According to police, an investigation remains ongoing.
