Louisa County, Virginia, officials say that a father and son visiting Lake Anna died by drowning over the Memorial Day weekend.

The incident happened at around 1:10 p.m. Saturday in the area of Carrs Bridge Road, according to a statement from the Louisa County Sheriff’s Office.

“While en route, deputies were advised that the father of the child had attempted to locate/rescue his son,” the department said. “It was reported that witnesses observed the father struggling, just before losing sight of him as well.”

Several people attempted to find the 42-year-old man and the 14-year-old boy before officials arrived, but they were unsuccessful.
