Campbell is charged with the death of his fiancee, Heather Domenie, at their Cary home last July. Domenie, a 33-year-old Raleigh school teacher, was foundstrangled to death.
Campbell has already admitted responsibility in his fiancee's death, but he claims he did not intend to kill her. Campbell's lawyers also said that the state did not meet the requirements needed to find Campbell guilty of first-degree murder.
Prosecutors claim Campbell killed Domenie to collect on insurance money and to be with another woman.
Both the prosecution and defense gave their closing arguments to the jury Thursday morning. Jurors will continue their deliberations starting at 9 a.m. Friday.
If convicted of first-degree murder, Campbell could face life in prison or a death sentence. If convicted of voluntary manslaughter, as his lawyers suggests is the correct verdict, Campbell could face as little as four years and three months in prison.
