Two Shreveport teenagers were killed in the three-vehicle crash on Interstate 20 that clogged traffic for hours Friday.
Louisiana State Police say 17-year-old Arien Manshack, the driver of a Buick LeSabre that crossed the median and struck another vehicle, was pronounced dead at the scene.
Authorities identified the other fatality as Megan Mote, 16. She was a front-seat passenger in the LeSabre that was heading east about 2:30 p.m. just east of Hwy 157.
Mote was flown to LSU Health where she later died, authorities say.
Investigating troopers say they haven't an explanation for why Manshack's car crossed the median. They explain that afterward, the LeSabre struck a Toyota Sequoia driven by April Walker, 41, of Minden.
After that collision, troopers say Manshack's car continued east and struck a Peterbuilt truck driven by Richard Cook, 51, of Laurel, Montana.
The LeSabre stopped in the westbound lanes of I20 after the second collision. The Sequoia stopped upon impact. Cook managed to stop his Peterbuilt on the shoulder of the westbound lane.
Neither Walker nor Cook was injured, troopers say.
As part of the continuing investigation, troopers say they have taken toxicology samples from the drivers for analysis.
