Two women who died in Lake Tuscaloosa last weekend were electrocuted, authorities announced Wednesday morning.

The Friday deaths of Shelly Darling, 34, and Elizabeth Whipple, 41, have been ruled accidental, Tuscaloosa County Metro Homicide Unit Capt. Kip Hart said. The final autopsy report will not be available until all tests are completed, he said.

Darling and Whipple were found dead in Lake Tuscaloosa early Saturday morning after they were reported missing by family members. Hart said a Tuscaloosa investigator was shocked during the initial search at the scene on Saturday but was not injured. "We know there was electricity going through at least part of the pier," he said at a Monday press conference. "We're waiting on full report from medical examiner to determine exactly what happened."

Electrocution has been suspected as the cause of death. Authorities said they know a current was running through the dock, but are still waiting on a report from the city inspector.

Whipple was the interim director of the domestic violence clinic at the University of Alabama School of Law. Darling, a native of Vestavia Hills, was a clinic staff attorney at the University of Alabama School of Law.

The Tuscaloosa County Metro Homicide Unit was called to the 15000 block of West Winds Drive in Northport on Lake Tuscaloosa at around 12:30 a.m. to the report of a possible drowning. Hart said Darling's family members called police when she didn't return home for dinner.
