An Effingham County woman and her mother died in a crash on Old Augusta Road Sunday afternoon.

Two other people were seriously injured when a pickup truck crossed into the path of a van shortly before 4 p.m., not far from the Mallard Pointe subdivision.

The two people in the van were pronounced dead at the scene, according to the Effingham County Sheriff's Office. They were identified as Megan Kessler, 30, of Rincon, and Kessler's mother, Marlys Strempke, 54, of Allenhurst.

Kessler was a special education teacher at Effingham County High School. She was in her eighth year teaching at ECHS, according to her bio on the school's Web site.

Kessler was from Hinesville, according to her Facebook page. She was married with three children.

Two people in the pickup, both teenagers, were taken to Memorial Heath University Medical Center with “what appear to be possible life-threatening injuries,” according to ECSO spokesman Detective David Ehsanipoor. One was flown by Life Star helicopter to the hospital and the other was taken by ambulance, Ehsanipoor said.

Karlie Miles, 19, was driving the truck and her passenger was Ivey Castaneda, 15, according to the ECSO. Castaneda is a student at Effingham County High School.

Old Augusta Road South near Georgia Pacific was closed as the ECSO and Georgia State Patrol investigated the crash. The road reopened around 8:45 p.m.

This crash comes one week after two people died in separate single-car wrecks in Effingham County during the Labor Day weekend.

“Unfortunately, here we go again,” Ehsanipoor said. “This is four fatalities within just the past seven days. It’s just a tragic crash.”
