A rear-end crash in Marietta on Tuesday morning sent the driver of a sedan to a hospital with life-threatening injuries.

A passenger in the Mercedes-Benz sedan was also injured when the impact of the collision sent the vehicle spinning into a sign and a utility pole, according to Marietta police.

The passenger, identified by police as 21-year-old Iyanna Miller of Marietta, was taken to WellStar Kennestone Hospital. She is expected to survive, Marietta police spokesman Jared Rakestraw said.

The driver, whose name was not released, is also being treated at Kennestone.

According to investigators at the scene, the Mercedes was traveling south on Powder Springs Street approaching Club Drive when it collided with a Nissan Rogue. The sedan slammed into the Nissan’s bumper before starting to spin.

The driver and a passenger in the Nissan, 52-year-old Marvin Coates and 42-year-old Lucyanne Ndungu, both of Marietta, were not seriously injured.

The department’s traffic unit is investigating the crash. Anyone with information is asked to contact Sgt. Brian Honea at 770-794-5344.
