The force of a double fatality crash on Saturday sent a Chevrolet across two lanes of traffic and onto a curb, police said.

A Norcross couple in the Chevrolet, both in their 80s, died from injuries and the 17-year-old driver of a Toyota was arrested after being treated for minor injuries at the scene of the crash, Cpl. Deon Washington said.

Alen Beganovic, 17, of Lawrenceville, was traveling south on McKendree Church Road toward Duluth Highway, when he swerved to the left to avoid hitting a vehicle that was stopped at a stop sign, Washington said.

After swerving, Benganovic drove through the stop sign and traveled across five lanes of traffic before crashing into the driver’s side door of the Chevrolet. The impact of the collision pushed the Chevrolet across two lanes and onto a curb, Washington said.

The driver of the Chevrolet, Frankie Turner, 80, was initially unresponsive, Washington said. Her husband, James Turner, 83, was conscious after the collision, but seriously injured.

Both were transported to Gwinnett Medical Center in Lawrenceville for treatment.

James Turner died several hours after the crash and his wife died Sunday, Washington said.

Benganovic faces between three and 15 years if indicted and convicted of vehicular homicide in the first degree, Washington said, but the district attorney and a judge will make final sentencing decisions.

The 17-year-old is also charged with reckless driving, failure to obey stop sign, failure to maintain lane and serious injury by vehicle, which would likely be dismissed if he is indicted on the homicide charge, Washington said.

Beganovic bonded out of jail on Saturday shortly before midnight.
