CHARLESTON, W.Va. -- Students at South Charleston High School wore green on Tuesday because it was Amber Williamson's favorite color. Some even wore T-shirts with messages like "Rest In Peace Amber," Principal Mike Arbogast said.
"We don't have answers for the kids, we just ask them to remember the great things about her. She was an honor student, and she excelled in writing. She had a very bright future ahead of her," he said.
Williamson, a 15-year-old honors student at SCHS, left a note then walked into the path of an oncoming train just past midnight Sunday morning in South Charleston.
In the past couple days, crisis response counselors have been in and out of the high school, talking to Amber's former classmates and leading therapeutic activities, like encouraging students to write about her and pass their messages on to her family.
"I've taught for 29 years, but I've never dealt with something like this. We are in awe of this tragic event, and we are thinking of and praying for her parents and her family," Arbogast said.
Amber had a 4.1 grade-point average. She was passionate about animals and loved music, traveling and planning parties, according to her obituary.
Katie Peal, a freshman at SCHS, was among the students who attended a vigil in Amber's memory Tuesday evening at the school.
"She was really nice and intelligent. She was always welcoming. Everyone loved her and her style. A lot of people were crying today. It was a hard day," said Peal, who also attended Dunbar Middle School with Amber. "Everyone was really shocked because she didn't seem like the type of person to do something like that. A lot of us wish we could've helped her with her problem. It wasn't worth her taking her life."
Students at SCHS showed an outpouring of condolences on social media sites -- even creating a "We love you Amber" Twitter account.
"I started bawling when I saw Amber's empty seat in class ... Can't this just be a bad dream?" one post read. "I was calm until I saw a train go by, and I lost it," said another.
