Dianna Creech Mahan Killed in Car Accident in Leon County, TX
Leon County, TX — September 9, 2023, Dianna Creech Mahan was killed following a single-vehicle car accident at around 3:00 p.m. along F.M. 3.
Preliminary information about the crash said that it happened in the area of Farm-to-Market 3 mile marker 390, which appear to be west of Normangee near county Road 465.
Investigators said in their statements that 73-year-old Dianna Creech Mahan was in a Toyota 4Runner which was going westbound along the roadway. The vehicle ended up going off the side of the road for some distance before eventually crashing into a tree. Mahan died as a result of the crash, authorities said.

While further evidence would be necessary to confirm, authorities claimed that a toxicology test showed the victim was over twice the legal limit following the crash. I don't at all bring this up to criticize the victim. In fact, my concern is whether or not authorities continued their investigations after learning this information.
Let me explain what I mean. I've handled many wrongful death cases involving alcohol where it turned out a local alcohol provider illegally over-served the victim. In a lot of those situations, the victim's loved ones didn't even think of a negligent establishment being involved. Authorities never mentioned such a possibility. It was only after our investigations that the businesses were brought to light. In fact, authorities would then use our information to begin their own investigations into the business and whether or not to file charges against the servers.
This is just a possibility, of course, and perhaps authorities here have been more thorough behind the scenes than public statements would suggest. But I've seen too many reports similar to these that were a sign authorities simply tested for alcohol and moved on without so much as a second thought. If that happened here, what more could there be to this story that authorities may have missed?
