Police were called to a West Melbourne, Florida, home Sunday afternoon.

Police said the deaths are suspicious but did not release a cause for the deaths. One of the infants was taken to a nearby hospital Sunday and the other was pronounced dead at the home.

“It is something that is very serious. We will methodically investigate this to try to get the answers that the children here deserve,” said Cpt. Richard Cordeau of the West Melbourne Police Department.

Thomas is being held in the Brevard County Jail on $30,000 bail.

Neighbors said Thomas lived at the home with her mother and kept to herself. They said they’ve only seen one infant and an older child with Thomas.

Melbourne police and the Department of Children and Families said they have not had any previous contact with Thomas. DCF has opened an investigation into what led to the deaths.

The infants’ siblings are being cared for by relatives.
