Alcohol and fog were contributing factors in a crash that killed two young people, Gwinnett County investigators said.

17-year-old Hope McKenzie and 20-year-old Austin Rogers after the teenager lost control of her car on Webb Gin House Road at Grayson Highway. McKenzie’s car sideswiped one vehicle and then hit an approaching pickup head on.

“We know that our two friends went quickly,” friend Cody Bacon said at Sunday night’s candlelight vigil. “Smiles on both their faces last time I saw them.”

McKenzie and Rogers were co-workers at a local Kroger. McKenzie was a senior at Grayson High School. Crosses and balloons have been placed at the spot where they died.

“Hope was well loved, very liked by such a huge amount of people,” Tony Sexton, whose daughter was friends with McKenzie, told Channel 2 Action News.

A third person in McKenzie's car suffered a broken leg.  The occupants of the truck also had to be hospitalized.  About a dozen people attended a candlelight vigil for the victims Sunday night at the crash scene.

The crash is still under investigation.
