Police in North Carolina are searching for the body of an Ohio mom after her ex-boyfriend confessed to his brother that he strangled her during a vacation trip.
So far police have been unable to find any sign of Lynn Jackenheimer, 33, or her ex-boyfriend Nathan Summerfield.
Summerfield, 27, has been called a "person of interest" in Jackenheimer's disappearance.
The former couple spent the week vacationing in Nags Head, N.C., with their 3-year-old son and Jackenheimer's 13-year-old daughter.
On Sunday, Summerfield returned to Ohio and dropped the two children off with family, when he reportedly confessed to his brother that he killed his ex-girlfriend.
"I want to report a possible murder. My brother was in North Carolina with his ex-girlfriend. He came back and said he strangled her and dropped his kid off and left," Jake Summerfield told an Ashland county dispatcher.
Police in Ohio, along with the Dare County Sheriff's Office in North Carolina, began coordinating an investigation and a search of the Nags Head area.
"I don't believe she is in Ashland County. I don't believe she ever came back from Nags Head," Carl Richert, a captain with the Ashland County Sheriff's Department, told ABC News' affiliate WVEC.
Steve Hoggard, chief deputy in Dare County, said no signs of Jackenheimer were found during an extensive search on Monday.
"We had a comprehensive search on the ground, air and with dogs," he said. "We didn't find anything."
Summerfield was last seen on Sunday driving a silver Honda Civic. Anyone with information is asked to contact the Ashland County Sheriff's Department at 419- 289-3911.
