Lynn Jackenheimer YouTube Appeal Aims To Catch Ohio Mom's Killer

Friends and family of Lynn Jackenheimer, an Ohio mom who was recently murdered while on vacation in North Carolina, are using the video-sharing website YouTube to appeal for information on her suspected killer.

A three-minute video clip featuring photos of the primary suspect, Jackenheimer's estranged boyfriend Nathan Summerfield, and his missing vehicle was uploaded to YouTube on Sunday. So far the video has been viewed more than 6,000 times.

"I just want to keep it alive," Jackenheimer's sister, Tasha Holland, told "I just want to keep it out there. He has all of our answers that we need to know, that I think we deserve to know."

Summerfield is the father of Jackenheimer's youngest child.

Jackenheimer, 33, was stabbed and strangled earlier this month. Her body was found dumped on Hatteras Island in North Carolina.

The mother of two was last seen alive on July 4, when she traveled to Nags Head, N.C., with Summerfield and the couple's 3-year-old son and her 13-year-old daughter, who has autism. Summerfield returned to Ashland with Jackenheimer's children on July 8, but she was not with them.

Police said Summerfield dropped the children off at a family member's house, and later confessed to his brother that he had killed Jackenheimer. His whereabouts since that time remain a mystery.
