South Texas police say a toddler has died at a hospital after she and her twin were found unresponsive in a bathtub.
Pearland police and paramedics responded Tuesday morning to a residence after a woman called 911 to say she found her two daughters, both 15 months old, in the bathtub.
Authorities say the twins were flown to a hospital, where one of the girls was pronounced dead. Her sister remains in critical condition.
Harris County medical examiners will conduct an autopsy to confirm the deceased child's cause of death.
Police say it's too early on in the investigation to announce whether they suspect foul play.
