An 18-year-old faces vehicular homicide charges after authorities say he slammed an SUV carrying three other people into a brick mailbox, killing a teenage passenger.

Steven Kyle Timms of Cedartown also faces charges of driving under the influence of drugs, possession of marijuana contributing to the deprivation of a minor, reckless driving, failure to maintain a lane, a seat belt violation and driving too fast for conditions in the Thursday evening wreck that killed 15-year-old Kemarion Washington, according to the Georgia State Patrol.

Timms remained in the Polk County jail Friday without bond.

Washington was a rising 10th-grader at Rome High School. His 12-year-old brother, Brent Washington, was also injured and remains at Children's Healthcare of Atlanta at Egleston in critical condition, according to the Rome News-Tribune. Brent Washington is a rising seventh-grader at Rome Middle School.

About 11 p.m., the boys were in a 2012 Nissan Rogue on Kimwood Drive when Timms lost control turning through a curve and hit a brick mailbox nearly head-on, according to the GSP.

“The Rogue overturned several times in the roadway before coming to a final rest, on its wheels, off the east shoulder in a ditch facing east,” the GSP said.

Timms and a fourth passenger, 17-year-old Devin Maddox, were not injured. Authorities told the News-Tribune the two had to be extricated from the car following the wreckage.

The GSP told the newspaper that Timms was driving 70 mph in a 35-mph zone.
