Overview
- Laura Nicholson, 23, was taken into custody in Florida and booked into the Lee County Jail on two counts of injury to a child, according to the Harris County Sheriff’s Office.
- Investigators said both girls tested positive for cocaine and the cocaine metabolite benzoylecgonine in toxicology results released by county forensic officials.
- The medical examiner said the autopsies could not confirm or rule out drowning, noting that such determinations often rely on the surrounding facts.
- The sisters were found in the backyard pool at their Katy home by their grandmother, and first responders tried to save them before they were pronounced dead at a hospital.
- Court records describe a broken back-door latch, prior unsupervised access to the pool, and Nicholson’s statement that she had fallen asleep, while investigators still have not determined how the children were exposed to cocaine.
