Two Years Later: John and Liz Calvert Case

Still no clues to the whereabouts of John and Liz Calvert of Hilton Head. Wednesday marked two years since their disappearance. The couple managed the Harbourtown Yacht Basin at Sea Pines. They were last seen with their Accountant, Dennis Gerwing, who was named a person of interest in the case. A day after that, he committed suicide, leaving behind a note admitting he embezzled money but left no clues of where the couple may be.

While the loss of two friends and the mystery around their disappearance rocked this community two years ago, as time passes, life goes on. But there's something about this case, folks haven't let go. Beaufort County Sheriff PJ Tanner reminded of that quite often.

“Almost daily,” Tanner said.

An update Tanner hates to report: the results of the soil sample found inside Dennis Gerwing’s home was no help to the investigation.

"There was not enough soil to analyze to give us any geographical location so we're back to square one on that,” Tanner said.

Tanner wanted evidence to support his theory that Gerwing had taken the couple a few hours from the Hilton Head.

"And my feeling has always been they're three, four, five hours from here because there was an 11 hour window that Dennis Gerwing's phone was powered off,” Tanner said.

But if there's any new hope, it came last month from a group of retired law enforcement officers who volunteered their help.

"We created a Beaufort County Sheriff's Office Cold Case review team and we gave them the Calvert investigation we gave them the entire case,” Tanner said.

"The thing that we found- the common denominator out of all this- was there were people and there are still people in the Calvert investigation that we were suspicious of-not persons of interest like Dennis Gerwing-but just didn't fit--and it appears that the cold case review team felt the same way,” Tanner said.

Tanner meets again with the review team Thursday.
