OWENSBORO, Ky. -- A female inmate at the Daviess County Detention Center got pregnant while incarcerated there, apparently after crawling through ductwork to meet with a male inmate, jail officials said.

Melissa Haycraft, 25, of Lewisport, and John Benson, 24, of Owensboro are accused of sneaking into a plumbing crawl space at the jail and returning to Haycraft's cell during the overnight hours of Jan. 10-11, Daviess County Jailer David Osborne said.

Haycraft has since been transferred to the Kentucky Correctional Institute for Women in Pewee Valley, an all-female prison, where her health care needs will be met, said Lisa Lamb, spokeswoman for the Kentucky Department of Corrections.

Haycraft's cellmates reported the encounter to jail officials.

Both inmates were questioned, but denied any sexual activity, Osborne said. Benson told investigators that Haycraft gave him food and that they kissed, he said.

The investigation resulted in both being charged with administrative violations of attempted escape, lying to a jail deputy and interfering with the safety and security of a facility.
