The State Medical Examiner's Office confirmed Wednesday morning that 25-year-old Jaymie Adams was pregnant when she died.
Adams' husband, Justin, had said previously his wife was pregnant, but the information was confirmed during the autopsy.
According to Oklahoma City Police, her unborn child will now be considered the city's second homicide of 2012. No suspects or persons of interest have been named in the case.
The mother of three was last seen Friday, December 9. Her van was found in a McDonald's parking lot in Midwest City. Her husband told police Jaymie was involved in online prostitution and had gone out to meet two or three men for sex.
