Preliminary toxicology reports show both drivers in a head-on collision early Saturday on Route 50 were drunken driving, Maryland State Police said Tuesday.

Police have been investigating the Anne Arundel County accident that killed Terry Davis, 55, of Severna Park, who was driving a BMW convertible, and Brittany Ann Walker, 19, a 2010 Meade Senior High School graduate who was driving a Chrysler Sebring the wrong way in an eastbound lane of the highway near Davidsonville Road.

Also killed were Walker's passengers, Breanna Marie Franco, 18, and Zachary Tyler Rose, 18. Rose was a 2011 graduate of Meade High and Franco graduated from Severna Park High School in 2011

Police haven't reported a reason that Walker was driving the wrong way on the divided highway. Authorities had received several 911 calls to report a car speeding south on Interstate 97 and then on U.S. 50 shortly before the accident.
