North Carolina ? The wife of the key suspect in the slaying of a 20-year-old pregnant Marine waited almost 24 hours after learning of the woman’s death to go to authorities, according to court documents released Thursday.

The sheriff’s affidavit, which details the account Cpl. Cesar Armando Laurean’s wife gave to detectives, does not provide an explanation for why she waited. Police have consistently described her as a cooperating witness, and she does not face charges.

Laurean told his wife, Christina, while driving to their attorney’s office last Thursday that Lance Cpl. Maria Lauterbach visited the couple’s home on Dec. 15, demanded money and told him she planned to leave the area, according to the affidavit.

Lauterbach had accused Laurean of rape in May, a charge he denied to military investigators.

Laurean asked his wife whether she was “with him on this” as they headed to the attorney’s office, according to the affidavit. She responded: “I do not know. Is there anything you have not told me?” That’s when Laurean told her what had happened, the affidavit states.
