JONESBORO, Ga. -- The parents and grandmother of a set of twins are facing child abuse charges in Clayton County.

Police said the grandmother of the infant twins found them malnourished and their parents passed out when she visited their house at 31 Lacosta Drive in Lovejoy on Tuesday, November 20.

The grandmother, 51-year-old Christi Zelek, took the 13-month old twins to the home of another family member, according to a release from Clayton County police.

Police say she then returned to the Lovejoy house and cleaned up before calling authorities.

The parents of the twins, James McCart, 23, and Tessa Zelek, also 23, were taken to Henry CountyMedical Center where McCart tested positive for cocaine. Tessa Zelek refused a drug test.

Police arrested all three adults on Thursday and charged them with cruelty to children and contributing to the deprivation of a minor.

Christi Zelek who is a special education coordinator with the Henry County school system was also charged with failure to report suspected child abuse. As an educator, state law requires her to report suspected child abuse.

The twins are being treated at Egleston Children's Healthcare of Atlanta where they will remain until they are healthy enough be placed in a foster home.
