Nassau County District Attorney Kathleen Rice said there has been a lot of speculation as to what caused the horrific crash.

Sources told CBS 2 Beer has admitted the group was smoking marijuana before the crash.

“Blood from the driver has been sent to a lab to be screened for alcohol and drugs. While we hope to expedite those tests, the results may not be available for some time,” she said Wednesday.

Rice said because Beer was driving a Subaru, her office has also contacted the car company.

“To determine if the vehicle had a black box from which data about the vehicle’s speed can be downloaded,” Rice said.

She said that, right now, no criminal charges have been filed.

Beer was driving with a learner’s permit. However driving with a learner’s permit is only allowed if someone 21 or older is in the car at the time.

So far, no criminal charges have been filed, but an announcement about the case is expected to be made later today.

The Southern State Parkway is one of the deadliest roads in the area, WCBS 880’s Mike Xirinachs reported. AAA said that’s due to poor lighting, heavy traffic and frequent speeding.
