DALLAS - Authorities say alcohol may have played a role in a seven-vehicle crash that killed two and led to one arrest Tuesday morning in Dallas.
The southbound lanes of Interstate 35E at Illinois Avenue were closed temporarily as authorities investigated the deadly crash that happened just after 5 a.m. Three people were transported to area hospitals. Their conditions are not known.
The Dallas County Sheriff's Department said one person was arrested and they are looking into criminal negligence homicide charges. They have not released the name of the person arrested. While authorities said they are investigating whether alcohol played a role in the crash, earlier in the morning they said they were also looking into the possibility that some of the drivers were racing.
Traffic could be seen backed up throughout the morning as part of the interstate was shut down. Some drivers could be seen crossing through grass and going the wrong direction on at least one highway service road in an attempt to get out of the traffic.
The interstate was re-opened around 9:30 a.m.
