wptv:The siblings were with a parent who was visiting friends at the home.
The sheriff's office said the children were described by the parent as experienced swimmers and proficient divers and had been to this home on past occasions.
The brother and sister were given permission to use the pool, along with a scuba tank, while the adults conducted their business, according to the investigators.
Once the scuba tank was placed in the pool, the children followed, and the adults told detectives they walked away from the pool area into the garage to look at another piece of equipment.
After leaving for a short amount of time, an adult returned and found both children at the bottom of the pool with the tank.
