Godley police are investigating a deadly hit-and-run along Farm-to-Market Road 2331 near County Road 1230 Friday morning.
Police said they received a call at about 1:30 a.m. about a one-car crash. When officers arrived, they saw a woman in the road who had been struck.
The person who hit her did not call 911 or stop to help. The hit-and-run is now a criminal case.
The woman, who was later identified as 49-year-old Carrie Fitzgerald, was driving a Chevrolet pick-up when she lost control on the unlit two-lane undivided highway and rolled over, according to authorities.
Officials said the woman was laying in the roadway when she was hit by the hit-and-run driver. The medical examiner told police it may be difficult to determine if the woman was killed in the first crash or if she died after being run over.
Police say they have no witnesses at this point.
Based on skid marks seen by officers, the driver that hit the woman might have been driving an 18-wheeler, according to police.
Authorities said alcohol does not appear to be a factor.
The Texas Department of Public Safety is also involved in the investigation.
