The coroner in Crittenden County pronounced three people dead in a crash Sunday.
The Nissan SUV in which the family was riding was crushed when it ran under a tractor-trailer.
State police say the driver, 26 year-old Nicholas McGuire of Gosnell, Arkansas, failed to stop in a construction zone. His wife, Jessica, and daughter, Brinley, also died on the scene. Six year-old Cadence McGuire survived.
This is the same stretch of I-55 where two construction workers were killed back in April when a pick-up lost control while they were on the job.
