An 11-year-old south Forsyth girl has become the second person to die as a result of a two-vehicle wreck Wednesday.

According to the Forsyth County Sheriff’s Office, Caroline Addlesburger died about 10:25 a.m. Friday at Children’s Healthcare of Atlanta at Scottish Rite. She was a student at Riverwatch Middle School.

Addlesburger’s mother, Tracy Bieler, was killed in the collision, which occurred during heavy rain Wednesday morning on Old Atlanta Road near Sharon Road in south Forsyth.

A second 11-year-old girl, identified as a family friend, was taken to Children's Healthcare of Atlanta with what authorities described as non-life threatening injuries to her face.

Addlesburger was the front seat passenger and the other girl was riding in the back seat of the 2002 Toyota Camry driven by Bieler, according to the sheriff’s office.

The wreck occurred about 11 a.m. Wednesday when the southbound Camry crossed the centerline in a curve on Old Atlanta and was struck broadside by a 2012 Honda Odyssey, the sheriff’s office said.

The driver of the Honda, 40-year-old Mujtaba Syed of Cumming, was taken to North Fulton Hospital with non-life threatening injuries.

A 7-year old passenger in the van was treated for a broken leg, also at Children's Healthcare of Atlanta, according to the sheriff’s office.

Forsyth County Schools spokeswoman Jennifer Caracciolo has said that counselors were available at both Riverwatch Middle and Settles Bridge Elementary, which Addlesburger previously attended, to work with students and staff who are close to the child.

Authorities have said that the weather was a contributing factor in the collision. No charges have been filed, and the investigation continues.

It was the first fatal wreck of the month on county roads and 12th of the year. Three people were killed in separate collisions over a six-day span July 22-28.
