The 29-year-old is scheduled to be sentenced February 4 for his guilty pleas to charges of aggravated manslaughter and hindering apprehension, according to the office of Burlington County Prosecutor Robert Bernardi.

He remains in the Burlington County Jail, with bail set at $1,200,000.

Erica Crippen's disappearance came to the attention of school officials when no one arrived to take her seven-year-old daughter home for the day. The youngster, froma previous relationship, lived with the couple along with their three-month-old daughter.

School officials requested a wellness check. Crosby subsequently signed a missing-persons report, averring that he had not seen his wife since January 1. Nine days later, citing the level of care given to the children in his wife's absence, authorities charged him with endangering the welfare of a child.

On January 12, just about two weeks after Crippen was last seen, Crosby was arrested by Brooklawn police during a traffic stop. The next day, he was charged with murder for her death by asphyxiation.

Burlington County investigators, Mount Laurel Police and Maryland State Police conducted three searches in Maryland for her remains.

Authorities said that the global positioning system in Crosby's car after his arrest indicated that of the areas he visited, he spent the most time in Carroll County, along Old Frederick Road in Sykesville.

Crippen's body was found March 17 in the a pine grove in Sykesville, beneath branches and tree limbs, wrapped in a blanket, bound at hands and feed with a cord that attached to her neck, mouth and nose covered in duct tape.

Crosby must serve 85 percent of the term before parole consideration, in accord with New Jersey's No Early Release Act.

As part of his plea bargain, Crosby's mother, Jo Crosby, 68, of Sicklerville, will have charges against her dismissed at sentencing. She was charged with hindering apprehension and with tampering with or fabricating physical evidence. She is free on $12,500 bail.
