Five people were killed in two separate crashes in Anne Arundel County early Saturday, according to police.

About 3:30 a.m., a vehicle traveling in the wrong direction on Route 50 east struck another vehicle head-on one mile east of Davidsonville Road, causing one of the vehicles to catch fire briefly, according to Maryland State Police.

Three people died at the scene, and a fourth person died on the way to the hospital.

The vehicle going the wrong way was carrying Breanna Marie Franco, 18; Brittany Ann Walker, 19; and Zachary Tyler Rose, 18. Walker, who is from Hanover, was the driver, police said. Police were withholding the fourth victim’s identity until relatives could be notified.

The police said several calls were received about a vehicle going the wrong way on Interstate-97 and Route 50, but they have not confirmed that it was the same vehicle that was found to be involved in the crash. Police are investigating how the vehicle ended up in the wrong direction.

The crash closed Route 50 east for about four hours Saturday morning.

Shortly after midnight, Brian David McDevitt, 32, of Pasadena died after his 2003 Acura went out of control on Fort Smallwood Road in Pasadena. The car struck another vehicle and overturned into a ditch, ejecting McDevitt, according to Anne Arundel County Police.

Two passengers in the second vehicle suffered minor injuries, police said.

According to the Baltimore Sun, McDevitt was one of the founders of a Facebook page called “Anne Arundel County Breaking News and Events,” featuring traffic and accident updates, among other community news.
