A motorist was killed and his passenger critically injured overnight in a single car wreck in Roswell.
The crash happened late Sunday night on Riverside Road near Northcliff Trace.
Roswell police spokeswoman Lisa Holland told the AJC that the Honda Accord left the roadway shortly before midnight and struck a tree with a "horrific impact," killing the driver, identified as Samuel Wiggins, 20, of Roswell.
His passenger, 19-year-old Dylan Rigsby, was hospitalized in critical condition.
Holland said investigators intitially believed the driver and passenger were brothers, but later learned they were roommates.
She said excessive speed was a factor, and investigators were awaiting toxicology results to detemine whether alcohol or drugs played a role in the crash.
