The Detroit Police Department is investigating after three teens were injured in a triple shooting early Saturday morning. Captain Shannon Hampton says shortly before 3 a.m. on July 5, police received a Shotspotter alert in the area of Acacia Avenue and Bentler Street.

We will ... work with ... our law enforcement partners to investigate how these firearms end up in the hands of our children," Prosecutor Ryan Mears said.

Four teenagers are being criminally charged following a mass shooting that broke out in downtown Indianapolis as Fourth of July celebrations were winding down.

More people are expected to be charged in the coming days as police and prosecutors continue investigating and pursuing criminal charges.
