A Georgia mother and her twin 10-month-old infant sons were found in a submerged vehicle that was pulled from a pond, officials said Saturday.

A fisherman found the car in Mayor’s Pond in Augusta on Friday and called police, said Richmond County Coroner Mark Bowen, according to the 360aproko news.

Authorities identified the bodies as Shaquia Philpot, 25, and her infant children Caysen and Cassius Williams. All three were pronounced dead at the scene, Bowen said.

Investigators did not release details about how the family ended up in the pond.

No cause of death has been released. The bodies were sent to the Georgia Bureau of Investigation for an autopsy.

The case remains under investigation.
