South Dakota Attorney General Jason Ravnsborg reported hitting a deer with his car on Saturday night but actually killed a pedestrian whose body was not found until the next day, state investigators said Monday.

The Department of Public Safety issued a statement Monday that said only that Ravnsborg told the Hyde County Sheriff's Office that he had hit a deer with his 2011 Ford Taurus.

Kristi Noem had revealed Sunday that Ravnsborg was involved in a fatal crash and said the Department of Public Safety was investigating, but neither she nor the agency had provided any details about what happened.

"I am shocked and filled with sorrow following the events of last night," Ravnsborg said in a statement late Sunday.

The Department of Public Safety says its investigation is ongoing.

Victor Nemec told CBS affiliate KELO-TV that he questions whether or not a 911 call was made because no sirens were heard leaving Highmore Saturday night.

South Dakota Attorney General told Hyde County Sheriff's Office he had hit a deer Saturday night following crash that killed one man.

"My worst fear is that they're trying to get ducks in a row to absolve the attorney general of any wrongdoing," Nick Nemec said.

The attorney general is known to be a frequent attendee of the fundraisers known as Lincoln Day Dinners, hosted by county GOP groups across the state.

Bormann said the attorney general drinks occasionally, but has made it a practice not to drink at the Lincoln Day events.
