Derrick DiJon Page, 23, was shot at a large party on North Lake Street in Aurora, Illinois, on September 5, 2015, and died the next morning at Advocate Good Samaritan Hospital in Downers Grove. The shooting followed a disturbance that moved outside, with a fight reported on the east side of Lake Street; Derrick was struck in the back of the head while allegedly trying to help a friend leave the scene.

Derrick’s family described him as a peacemaker who had moved to the suburbs with his family to avoid Chicago violence. He had played football at Aurora University and was an aspiring musician who publicly advocated against guns and violence. The loss cut short plans he had as he approached his 24th birthday.

An arrest was later made in connection with the shooting. Does anyone have information about Derrick, the party that night, or who might help fill gaps in what happened?
