Witnesses told police a man was found unresponsive in a pool on the 100 block of Augusta Street before 1 p.m. and his adult son jumped in attempting to save him, Sgt. Brad Holmes said. The son described being "shocked" while in the pool, Holmes said.
"We can confirm that an electrical current was found in the swimming pool, however, the nature of the current is still under investigation," Holmes said in a news release. "It is our understanding that both men were resuscitated by medical personnel and are being transferred to acute care units within the hospital."
The names and ages of the victims haven't been released. Witnesses at the scene described the father as being at least 60 years old. The son was described as being in serious condition Friday evening, according to the WHNT-19 report.
The city's fire, building and electric departments are assisting police with the investigation.
"While we do not believe the incident is criminal in nature, we will continue to work with the family and city officials to determine the cause of the electrical current in the pool," Holmes said.
