Investigators are still trying to determine how two Texas siblings drowned in a pool at a Hillsborough County motel while on a Father's Day outing with their church.
Bystanders pulled 17-year-old Kesha Greco and her 12-year-old brother, Sebastano, from the Clarion Inn and Conference Center pool in Brandon on Sunday afternoon. Their parents, Kelly and Monique Greco, told Hillsborough County Sheriff's officials that both children could tread water but weren't strong swimmers.
The Tampa Bay Times reports Sebastano Greco was declared dead Sunday. His sister died Tuesday at a Tampa hospital.
Sheriff's spokeswoman Crystal Nunez tells the Times foul play isn't suspected but investigators don't know whether one sibling was trying to help the other.
The family is from Dallas and had traveled to Florida with the New Life Church of North Texas.
