A woman was kidnapped and reportedly thrown off a bridge after witnessing a murder.

Two men were shot at a house in Scott, Arkansas, early Christmas morning, authorities said.

Deputies arriving at the scene found that one man had been killed and a second had survived his gunshot wounds, according to Capt. David Bufford, a spokesman for the Lonoke County Sheriff's Office. The second man's girlfriend was missing from the residence and investigators issued a statewide bulletin, Bufford said.

Local station KATV reported that Little Rock Police found her in neighboring Pulaski County. According to a police report, the woman said she was thrown off a bridge into the river and then swam to shore. NBC News could not independently verify those details on Thursday.

The woman, who has not been identified, told investigators she witnessed a shooting at the home from which she was taken, Bufford said. She is doing "okay" and has been released from a hospital, where she was treated for hypothermia, Bufford added.
