Previously, 17-year-old Caleb Witt was killed March 26 and 16-year-old Jada White died March 29.

"We’re just dealing with a generation that is desensitized to violence,’’ said Birmingham police Officer Truman Fitzgerald, according to al.com. "That’s their first go-to, grabbing a gun."

Fitzgerald said there were people around when Phillips was shot and investigators believe there are witnesses who could help them.
