GREENSBORO — The Guilford County sheriff’s deputy involved in the Saturday night crash that killed five people on Battleground Avenue has been on the job just over a year and has received excellent field reviews, according to Sheriff BJ Barnes.

Deputy C. Lineback, 24, tried to pull over a reportedly stolen 2003 Acura with three people inside that sped down Battleground Avenue at 11:27 p.m. at more than 100 mph, before crashing into a 2012 Kia Optima with two women inside. A dog in the Optima survived.

The deputy at one point was going 108 mph, and the Acura was still pulling away from him, Barnes said.

“Traffic was light and there was a judgment call,” Barnes said of the officer’s speed.

He said previously that during a chase a supervisor would be tracking the speed, location and even the weather to determine whether to continue the chase or call it off. This chase had barely started when it ended about 70 seconds later in the deadly crash.

The sheriff said he stands by his deputy, who has not received any discipline.

A law-enforcement officer with more experience also would have tried to stop the car, Barnes said.
