AP: Video shows fatal crash

CHICAGO (AP) — Surveillance video obtained exclusively by The Associated Press shows two fast-moving Chicago police vehicles with their emergency lights on colliding at an intersection, then crashing into another car and killing an 84-year-old retired teacher.

The video was provided to the AP Monday by a lawyer representing the woman’s family. It shows a police van going through a red light and striking another police vehicle. Both then slam into the family car, killing Verona Gunn and injuring three others.

The Memorial Day weekend collision also injured 10 police officers. Authorities couldn’t say definitively who caused it because the investigation was ongoing.
