CROFTON, Md. (CBSDC/AP) — Maryland State Police say both drivers in a fatal wrong-way crash on an Anne Arundel County highway were under the influence of alcohol.

Police said Tuesday that toxicology reports showed that the drivers of the two cars that collided on Route 50 early Saturday, killing four people, had alcohol in their systems.

The three people in the car headed the wrong way, driver 19-year-old Brittany Ann Walker and her passengers, 18-year-old Breanna Marie Franco and 18-year-old Zachary Tyler Rose, were all killed. All three were former Meade High School students.

The driver of the other car, 55-year-old Terry Wayne Davis of Severna Park, died as he was being taken to a hospital.

WNEW obtained one of the 911 calls placed before the crash.

In the audio, a concerned and frightened driver reported a wrong-way driver in northbound lanes of Interstate 97 headed south toward Route 50.
