The five teens involved in a fiery crash Monday evening that killed four and injured one were all students at Gretna High School, the school's principal told parents in a letter.
Counselors are stationed at the school following the one-vehicle crash.
"I was informed last night that five of our high school students were involved in an accident at 180th and Platteview Rd," wrote Gretna High Principal Roger Miller. "Names have not been released yet to the public by the sheriff’s office so I cannot share that information with you at this time."
The crash occurred just west of the intersection of 180th Street and Platteview Road, according to Capt. Chris Culler of the Sarpy County Sheriff's Office.
Authorities believe that they know the identities of the deceased but are withholding their names pending confirmation. Culler said authorities may need to use DNA and dental records in the identification process.
The five people in the vehicle are all believed to be 15 to 16 years old.
"Counselors and staff have been available at the high school since 8:30 a.m.," said Kevin Riley, the Gretna Public Schools superintendent. "We will be there as long as it is necessary."
"It's the worst thing that can happen to a community," Riley said. "Over the years, this has happened, and it never gets any easier."
A link on the Gretna district's website directs parents and students to resources on death and grief.
Condolences have poured out on social media for the families and friends of the teens and the Gretna community.
A Sarpy County deputy tweeted out that it was a "tragic scene."
"Spent several hours at the scene and standing by with parents," wrote Sarpy County Sheriff's Deputy Nick Palmer. "Words can’t describe the trauma the families and Gretna community are going to deal with today."
Deputies were called to the scene at 11:12 p.m. and found a Ford Fusion engulfed in flames. Investigators determined that the Ford was eastbound on Platteview Road when it left the roadway for an unknown reason and struck the end of a guardrail, Culler said.
The vehicle continued down into a ravine and caught fire.
The crash occurred in a rural location about three miles east of Nebraska Crossing Outlets.
Four teenagers were pronounced dead at the scene. The fifth teen, a girl, was taken to Creighton University Medical Center-Bergan Mercy with burns before being transferred to St. Elizabeth Regional Medical Center in Lincoln.
A spokeswoman for St. Elizabeth said no information is being released about the surviving girl.
