RALEIGH, WAKE COUNTY -

The Wake County sheriff says six detention officers are no longer on the job as the result of an investigation into inappropriate relationships with inmates, including Amanda Hayes, who was convicted last month in the murder of Laura Ackerson.

Sheriff Donnie Harrison told WRAL-TV that one officer resigned March 3 after an internal investigation concluded she violated the office fraternization policy. That policy prohibits jail employees from having any kind of relationship with inmates outside the scope of their jobs.

He says the investigation in that officer's relationship with Amanda Hayes led to the firings a few days later of five other detention officers for similar behavior with other inmates.

Hayes was convicted last month of second-degree murder in the death of her husband's ex-girlfriend, Laura Ackerson, of Kinston. Hayes and her husband killed Ackerson in Raleigh and dumped her dismembered remains in Texas, investigators said.

Harrison says he found no evidence that the detention officers were having sex with inmates.
