Four teens, including a girl set to graduate Saturday from SouthWest Edgecombe High School and her brother, were killed in a wreck Thursday on U.S. 264 bypass outside of Greenville.

Madison and Devin Wilson were traveling on the highway when a truck crossed the median in rainy weather and collided with their vehicle, killing them and two others Thursday morning. A fifth teen was not injured.

Official details were scarce, but multiple sources said Madison, 18, and Devin, a ninth-grader, were among several SouthWest Edgecombe students in the car. Madison was set to graduate on Saturday.

The identities of the others involved were not available, and the State Highway Patrol had released little information Thursday evening. The truck driver reportedly did not suffer life-threatening injuries. The weather was a factor, according to reports.

A staff email from Edgecombe County Public Schools Superintendent Valerie Bridges said that “several” of those involved in the collision were students from SouthWest Edgecombe High School. Another teen involved was reported to be a Tarboro High School student.
