All of the department's fleet will get the cameras, the department has said. But their rollout will be done in phases, Granda said on Tuesday, with completion expected by the end of March. They were part of a package that the department bought to equip its officers with body cameras earlier this year.

But the police SUV has technology that lets the department check speed and other factors. So far, Granda said, "the data is consistent with the involved officer's statement."

The officer told police that he noticed a black Camaro acting suspiciously at a BP gas station near Halls Ferry Circle in Jennings, where the officer patrols. He ran the license plate and discovered it did not match the Camaro. The vehicle sped away from him southbound along Halls Ferry Road, and the officer "attempted to close the gap" between him and the car to make a traffic stop, Granda said.

The posted speed limit along that stretch of road is 30 mph, and the officer's maximum speed was 59 mph. It's not clear how fast the officer was driving when he hit the child, Granda said.

From start to finish, the officer chased the Camaro for 32 seconds and covered a quarter of a mile. He did not use his lights and siren because he was trying to catch up to the vehicle before doing so, Granda said.
