The investigation continues into this week's fiery one-car crash that claimed the lives of four Gretna teen-age girls and left a fifth girl hospitalized with severe burns.

The stretch of road near Springfield, just south of Omaha, now finds signs telling drivers to slow down.

According to the Sarpy County Sheriff's office, the temporary warnings were posted in order to help keep mourners leaving roadside memorials safe.

The crash occurred late Monday night when it appears the car left the hilly road and crashed into the end of a guardrail.

For the second straight day counselors were scheduled to be on hand at Gretna High School for students and staff grieving from the accident.

Officials tell News Channel Nebraska that although the five victims are well known in town, their names have not been officially released in order to avoid an unlikely case of mistaken identity.
