A Criminal Court jury convicted Martinos Derring on charges of robbery, theft of property over $1,000, intentionally evading arrest by auto creating a risk of injury or death, and evading arrest.
Derring, whose bond was revoked, will be sentenced Sept. 22 by Judge Lee Coffee.
The 54-year-old victim said that on shortly after midnight on Aug. 16, 2014, she was at a portable movie kiosk at 1845 S. Third St. when a gunman walked up behind her and demanded the keys to her maroon 2002 Nissan Maxima.
The gunman drove off with her purse inside the car, but minutes after a broadcast went out an officer on routine patrol spotted the car going northbound on Interstate 55. The officer followed the car as it turned east on Crump and then west on Mississippi.
When the officer turned on blue lights and the siren Derring accelerated, ran a stoplight at Danny Thomas and struck another vehicle. Derring bailed out of the Maxima, but was caught by officers at Danny Thomas and Vance after a foot chase.
The trial was handled by Asst. Dist. Atty. Kevin McAlpin.
