A South Carolina man and his daughter were killed after they were mistaken for deer and were shot during a New Year’s Day hunt, the authorities said.

The victims were among four hunters who “were attempting to move deer, also known as driving deer, near Barracada Road in Walterboro when two hunters were shot after being mistaken for a deer,” according to a statement released by the South Carolina Department of Natural Resources. It was not clear whether they were wearing brightly colored safety gear.

David Lucas, a department spokesman, said the details of the shooting would not be released until the investigation was complete. The department did not release the names of any of the hunters.

Richard M. Harvey, the Colleton County coroner, said the victims were Kim Drawdy, 30, and Mr. Drawdy’s daughter Lauren, 9.
