Authorities say 33-year-old Lynn Jackenheimer, of Ashland, went to the Outer Banks last week with her boyfriend, Nate Summerfield, and her two children but didn't return with them. Summerfield's brother called police to say Summerfield told him he strangled the woman.
Police said Summerfield returned his girlfriend's children to Ohio and left them with his family.
Jackenheimer has been missing since July 4. Police are looking for Summerfield, who's being described as a person of interest.
The Ashland Times-Gazette reports Jackenheimer's employer and other businesses have pledged rewards in an effort to get information.
