NORTH LITTLE ROCK (AP) — More than 100 North Little Rock students met with grief counselors Monday after four of their classmates were killed while driving to Florida for spring break.

Authorities were investigating the Saturday wreck that killed Robert Johnson, Laquinta "Shea" Lowe, Christopher Adams, all 17, and Terrance Duckworth, 18. The group was part of a three-car caravan headed to Florida for spring break when the sport utility vehicle they were in struck a northeastern Mississippi bridge, flipped and landed upside down in a creek.

All of the teens were wearing seat belts and alcohol wasn't a factor, police said.

School was out for spring break, but school counselors and pastors met with students. District spokeswoman Shara Brazear said counselors would also be available when students returned to class next week.

By Monday morning, nearly 2,400 people had joined a Facebook group commemorating the teens, with friends remembering their classmates "RJ, Ducky, Chris and Shea."

Johnson was a member of the school band, and Duckworth played football and was on the school's track team. Adams, Lowe and Duckworth were involved in a school group that performed community service.

The four were expected to graduate May 21, North Little Rock High School Principal Tracy Allen said after the crash.

"It's tough. It's very tough because you get to know these kids, they become near and dear to your heart," he said.
