DeKalb police had been patrolling the 1000 block of West Hillcrest Drive after a report of shots being fired Saturday night, according to the release.
While patrolling a parking lot, an officer saw a dark-colored SUV speed through the lot with a man chasing it, yelling for police to stop the SUV. Police asked the man why, but they received no response, according to the release.
The SUV sped east on Hillcrest Drive without its headlights on, and after an officer turned on his emergency lights and tried to catch up, the SUV sped through the intersection of Hillcrest and Normal Road – a four-way stop, according to the release.
Shortly after, a black 2005 Toyota Highlander was found at the scene where Walker was pronounced dead, according to the release.
The DeKalb County Sheriff's and Coroner's offices continue to investigate the crash.
