MONROE COUNTY, Ga. (WGXA) - A Cobb County man is dead after a fatal wreck in Monroe County.

In a media release, the Monroe County Sheriff's Office says the wreck happened on I-75 northbound near mile marker 191 Friday morning. When deputies arrived, a tractor-trailer was blocking the interstate, forcing them to shut down two lanes. Meanwhile, 911 operators started to get calls regarding another accident, south of where deputies were. The second crash involved three tractor-trailers near the weigh station.

The Sheriff's Office says Maddyel Llanes, of Cobb County, was driving one of the tractor-trailers in the second crash. Llanes was killed in that wreck.

No other injuries have been reported.

The causes of both wrecks remain under investigation.
