Their four children, all younger than 15, have been placed in state custody.

Police were first called to the family's home on Starpointe Lane in January after reports of child neglect.

Coordinating with state Child Protective Services, police went to the home and found the children and their parents, all of whom tested positive for exposure to cocaine.

The couple were arrested May 3 and were indicted this week, police said.

"The children are currently safe and have been placed into CPS custody," police said Wednesday.
