Tanner Bertram, 22, was charged with second-degree vehicular homicide, a felony.
The fatal crash occurred at about 3 a.m. last Friday in the westbound lanes of North Marietta Parkway, between Wallace Road and Interstate 75.
The initial on-scene investigation revealed that Matthew Tyner, 20, of Marietta was walking west bound on the North Marietta Loop, in the right-turn lane, according to police.
Tyner was struck from behind by a late-model Kia Spectra, a subcompact car, which left the scene of the crash, police said.
Tyner was transported to WellStar Kennestone Hospital via Metro Ambulance, where he was pronounced dead.
As of two weeks ago, there were 84 pedestrian-related collisions investigated by Cobb and Marietta police in 2013. There were 89 in 2012 and 97 in 2011.
Out of those 84 pedestrians hit by vehicles this year, 36 resulted in an injury and seven ended in deaths. There were seven deaths in 2012 and five in 2011, according to Cobb police reports.
For four days, police had been looking for a 2007 to 2009 Kia Spectra, either a hatchback or coupe, with right-side passenger front-end damage.
Bertram’s Facebook page had numerous pictures and posts about his white Kia Spectra dating back to July. In one post from October, Bertram commented on a picture of his tinted windows, saying they were “slightly too dark to be legal.”
The day before the crash on Dec. 26, Bertram posted on Facebook, “Nothing like waking up the day after Christmas and having brand new car parts sitting on the porch, finally got a new rear bumper for my car and a hood.”
