RALEIGH – A security company executive and his family members are among five people referred to local prosecutors to consider whether some contributions they made to Pat McCrory’s campaign for North Carolina governor were illegal.

The board voted unanimously Friday to send to the Mecklenburg County district attorney the names of CPI Security chief executive Kenneth Gill, his wife, his two daughters and a former employee.

A board investigator said the ex-employee alleged Gill reimbursed him for giving to McCrory’s 2008 gubernatorial campaign. The investigator said Gill’s family members have declined to sign affidavits stating they weren’t reimbursed for donations.

McCrory is running again in 2012.

Kenneth Gill’s attorney says his client wants to cooperate with the prosecutor’s investigation.

Campaign records show the five have given more than $20,000 to McCrory’s campaign.
