A nearly two-year-old boy died Sunday afternoon after being pulled from his babysitter's pool last week, according to East Tennessee Children's Hospital. His twin sister drowned in the same West Knox County pool Friday morning.

The twins were in the care of a babysitter at a home on Fox Lonas Road. She told investigators she began looking for the children when another child arrived at 10 a.m. She found them in the deep end of the swimming pool.

They were rushed by ambulance to the hospital.

The Knox County Sheriff's Office and DCS are investigating the incident.
