Preliminary autopsies of two women from The University of Alabama Law School who were found in Lake Tuscaloosa over the weekend suggest that electrocution was the cause of death.

Shelly Darling, 34, a staff attorney for the elder law clinic, and Whipple, 41, interim director of the school’s domestic violence clinic, reportedly went to the lake on Friday to sunbathe. When Darling did not return home for dinner, her husband contacted the authorities who searched through the night and found the women’s bodies early Saturday morning. 

According to the Tuscaloosa News, an investigator was shocked during an initial search of the dock near where the women were found. This, coupled with the autopsy findings, lead authorities to believe that the women died from electric shock drowning in which faulty dock wiring sends currents through the water, immobilizing swimmers.

On Monday, Premiere Service Company advertised on their Facebook page that they will offer free electrical dock inspections, according to the Tuscaloosa News.

Despite the initial autopsy findings, Capt. Kip Hart, commander of the Tuscaloosa County Metro Homicide Unit, said the investigation is still ongoing.

“We’re still awaiting a complete autopsy report…[and] we’re still doing investigations into how things happened,” Hart told the Tuscaloosa News. “Perhaps we can find a better determination of how this happened. It could be a combination of events or items they came into contact with.”
