Jean Soriano, 18, appeared before a Moapa Township judge to hear five counts of driving under the influence causing death, two counts of DUI causing bodily harm, and two misdemeanor charges of driving without a license and failure to reduce speed in the March 30 crash, KVVU Las Vegas reported.
Soriano and his 23-year-old passenger were hurt when the Dodge Durango he was driving rear-ended a Chevrolet Astrovan, which overturned, killing three brothers and two other family members. The van's driver and another passenger survived.

Soriano admitted he had been driving and told investigators he had "too many" Budweisers before getting behind the wheel. The police report said Soriano and his passenger were driving from George, Utah, to Las Vegas.
After the accident, Soriano was treated in a hospital and was immediately arrested upon his release. He is being held at the Clark County Detention Center in lieu of bail, which was set at $3.5 million.
