For the past two years, officers have been summoned to the mother's home seven or eight times.
Twice the police visits led to reports of possible child neglect or child maltreatment.
The state agency said it never found any evidence of child maltreatment or neglect and had no reason to remove the siblings from their mother's custody.
Velasquez is being held with a $ 2 million bond.
