Officials called off the search for missing survivors around 9 p.m. last night. Dive and search operations in the area of the crash are being conducted by the Mohave County Sheriff's Office with the assistance of the San Bernardino County Sheriff's Department.

The accident happened after sunset, making rescue efforts difficult, authorities said. Some people were found as much as a mile down river due to the rapidly moving water.

Officials are unsure if alcohol was involved, or the ages or genders of those who were injured.
