Fazekas, a 32-year member of the Gary Police Department, was shot earlier this month after following a vehicle he saw driving recklessly in Gary.
When the vehicle came to a stop, Fazekas activated his lights and left his vehicle "when he was ambushed by a barrage of gunfire," Gary police have said.
Fazekas took cover inside his vehicle, but he was struck by gunfire, police said.
Cooks was arrested later Monday in a nearby abandoned home. At the time, police said Cooks had a long criminal history.
