(CNN) The accidental death of a 2-year-old boy in Milwaukee on Sunday triggered a violent chain of events, eventually claiming the lives of three more people.

It all started with a birthday party that little Damani Terry was attending. During the family gathering, he dashed out into the street and was struck and killed by a GMC van, according to Milwaukee police.

The distraught driver, Archie Brown Jr., 40, immediately stopped and got out to tend to the boy. But it was too late, police said. Damani was dead.

Damani's alarmed family came running, including his older brother, 15-year-old Rasheed Chiles, police said. That was not the end of the situation.

Soon, two more people would also die: the driver and the teen were both felled by bullets fired by the same man, police said.
