According to officials, the two Orange High School teenagers died around 10:30 p.m. Saturday when the truck they were riding in lost control and hit a tree. Two other teens who were also inside the vehicle were seriously injured.
On Sunday, classmates, friends and family members gathered at the scene of the accident to mourn the loss of the two high school juniors.
"Kacie and Chase never judged anyone ... they never hurt anyone, they loved everyone ... they didn't deserve this," friend Mackenzie Elmers said.
Elmers said she was with Chamberlain just days after Christmas and said she still has a hard time believing the news.
"If they were wearing their seat belt, all of this could have been avoided," she said. "No one realizes how important it is."
Gene Williams' grandson, McCray Williams, was one of the teens injured in the accident. Williams' said his grandson and the other teen, Sam Whaley, are lucky to be alive.
Whaley reportedly attended Orange High School with Chamberlain and Underwood, while Williams attended Eastern Alamance High School.
Both teens are currently recovering at Duke University Hospital.
Meanwhile, authorities are still investigating the accident, but troopers have said speed was a factor in the crash.
