Police say a school administrator found dead in a sugar cane field was pregnant with the child of a former co-worker, who has been accused in the killing.

The Advocate (http://bit.ly/28ULORL) reports Baton Rouge Police cited findings from a crime lab report released Thursday.

Forty-year-old Lyntell Washington was found dead June 14 in Iberville Parish, west of Baton Rouge. Police have charged Robert Jovantie Marks with first-degree murder, first-degree feticide, child desertion and aggravated kidnapping of a child.

Marks is an assistant principal at Brookstown Magnet Honors Academy, where Washington worked as an instructional specialist.

Marks' lawyer, Lionel "Lon" Burns, denies Marks killed Washington.

Washington's 3-year-old daughter was found alone June 9 near her mother's blood-stained car. The daughter told detectives that "Mr. Robbie" hurt her mother.
