Authorities in Greenwood, South Carolina, arrested a man following a fatal collision on May 7, 2023, that resulted in the death of 46-year-old Davis McClendon. Investigators initially responded to a report of a road accident on a dead-end street just after 1 a.m., where they discovered McClendon’s body near his damaged BMW sedan. While first responders suspected a hit-and-run, sheriff's deputies began investigating the incident as a potential intentional act.

The investigation centered on the relationship between McClendon and Meredith Haynie, who had been dating for approximately six months. Haynie was estranged from her husband of 10 years, Bud Ackerman, a local auto body shop owner. According to Haynie, Ackerman had recently discovered the relationship and had contacted McClendon to ask him to stop seeing her until their divorce was finalized. On the night of the incident, Haynie reported that McClendon left a club to meet with Ackerman to discuss the situation.

Sheriff's investigators utilized an oil trail leading from the crash site to locate a suspect vehicle. The trail led to the home of Ackerman’s parents, where deputies found a white Ford F-250 pickup truck with a leaking undercarriage and a cracked grille. Lieutenant Matthew Womack of the Greenwood County Sheriff's Office stated that data extracted from the truck's "infotainment system" provided a timeline of the vehicle's movements, including speed, braking, and locations visited that night.

Data from the truck showed Ackerman had been driving near Haynie’s home and McClendon’s street earlier in the evening. The system recorded a hard braking event at 1:11 a.m., coinciding with the time of the collision. Investigators alleged that Ackerman’s truck sideswiped McClendon’s sedan and struck McClendon, who was standing outside his vehicle. Ackerman was arrested at approximately 6:30 a.m. that morning and charged with murder.

The legal proceedings impact the families of both men, including three minor children belonging to Ackerman and Haynie. A conviction for murder in South Carolina carries a minimum sentence of 30 years to life in prison, a outcome that would permanently alter the care and financial support for these dependents. Furthermore, the defense’s argument regarding state adultery laws and the victim's position in the road suggests that the legal resolution will hinge on the distinction between criminal intent and accidental death in a roadway environment.

The case sets a precedent for how law enforcement uses integrated vehicle technology to reconstruct events where there are no eyewitnesses. Drivers may notice that their privacy rights regarding vehicle data are increasingly subject to search warrants in felony investigations. The next steps in the legal process include a trial where a jury will weigh the digital evidence against the defense's claim that the collision was an accident caused by poor visibility on a dark road. A specific trial date was not reported in the source material.
