MADISON, Wis.—Police in Milwaukee arrested a second person in a shooting in which six people, including the two alleged shooters, were wounded right after a Juneteenth celebration wrapped up.

The two defendants, males ages 17 and 19, were arrested after Monday’s shooting outside the Greater Philadelphia Church of God in Christ, police said in a news release.

The other four people who were wounded are girls or women ranging in age from 14–18 years old, police said. All six of the people who were shot are expected to survive.

Investigators believe the shooting stemmed from a fight between several young women outside of the church, police said.

A Facebook Live video of the aftermath showed paramedics treating people with gunshot wounds on the pavement of Martin Luther King Jr. Drive, where thousands of people had filled the street for the city’s Juneteenth festival just 20 minutes earlier.
