Mowry and the boy continued to have sexual relations while the child was between the ages of 11 and 14, the department said.
A 25-year-old Florida woman has been arrested for sexual battery after an investigation into her highly illegal sex tryst with a minor three years ago, who was a 11 at the time, came to a close.
WFTS reports Mowry was arrested following the completion of an investigation. The Hillsborough County Sheriff's Child Protective Division is helping in the investigation.
Marissa Mowry and the boy are reported to have had sex in Hillsborough County, Florida, in January 2014.
Authorities have placed the woman's 3-year-old with a "responsible adult", the release stated.
Deputies said the baby, which is now almost 3- years old, will be placed with a responsible adult.
Mowry worked in food services at Busch Gardens before her arrest.
At the time, Mowry was 22 years old and the boy was 11 years old.
Mowry is held at the county jail without bail.
