A tractor-trailer hit and killed a Kentucky middle school teacher Friday in Middle Georgia when she and her two children got out of the family’s SUV after it spun out of control in the middle of the interstate, sheriff’s officials said.

About 1 a.m., Judith Stacy and the children ran to the shoulder of I-475 after her husband lost control of the family’s Honda Pilot, hit a guardrail and came to a stop in the center lane, Bibb County sheriff’s deputies said in a Facebook post.

The tractor-trailer, driven by Karamjeet Singh, 31, of Florida, hit Stacy, who died on the scene, according to the sheriff’s office. No one else was injured.

“(Phillip) Stacy is reporting he was forced off the road by another vehicle entering from Eisenhower Parkway,” sheriff’s spokesman Lt. Randy Gonzalez told the Macon Telegraph.

The family’s SUV was facing oncoming traffic when the coroner arrived.

“The car that caused it left,” Bibb coroner Leon Jones said.

No description of that vehicle was immediately available, Gonzalez said. The crash is under investigation.

Judith Stacy was an eighth-grade teacher at Beaumont Middle School in Lexington, Ky. She had taught at the school since 2009 and had been in education for 24 years, WKYT reported.

Fayette County Public Schools in Kentucky released this letter to families of Judith Stacy’s former students: “It is with a heavy heart that I write today to make you aware that our Beaumont family lost a wonderful friend and outstanding teacher very early this morning.”

Anyone with information is asked to call Bibb sheriff’s officials at 478-751-7500.
