Investigators with the Chattanooga Police Department’s Traffic Unit have arrested 21-year-old Ariel C. Campbell for the traffic fatality of James "Jimbo" Morgan.
The wreck occurred at 18060 I-24 eastbound on Oct. 26, 2012.
Ms. Campbell has been charged with vehicular homicide by recklessness.
Chattanooga Police earlier said Ms. Campbell's vehicle went out of control on westbound Interstate 24, causing a multiple-vehicle wreck that claimed the life of Mr. Morgan, 61, the owner of Morgan Motors.
The crash also clogged traffic on the freeway and nearby side streets for hours.
The incident happened near Rossville Boulevard. Witness statements and evidence indicated that a Chrysler Concord driven by Ms.
Campbell went out of control and struck the center concrete barrier causing a chain reaction of crashes.
Witnesses said she had her emergency lights on and was swerving in and out of traffic at a very high rate of speed.
A Chevy S-10 driven by Mr. Morgan swerved to avoid the other vehicles when his truck slid sideways and rolled over multiple times. Mr. Morgan was ejected from his vehicle and later succumbed to his injuries.
